"Who does your taxes...?"
- Louis Tully; Ghostbusters
Louis is the quintessential nerd. While a very good-natured guy, he sports a level of social awkwardness that eclipses even Egon's. He tries to be hip and cool, but never pulls it off (he would work out to exercise videos, but at double speed). He tends to be obsessive compulsive when it comes to matters of taxes. More often than not, conversation with him will eventually steer into tax or monetary matters. He's always willing to help out, sometimes with embarrassing results for him, and he'll always point out an opportunity to a friend where they can save money on something. He's also shown to be pretty good with children, a manner he admitted learning from owning a pet hamster.
Deep down, Louis really wants to break out of his humdrum little existence and be a hero. Even though his assault on the slime shell coating the museum was at best negligible, Louis still put his heart into helping out.
Despite his social handicaps, Louis is apparently a top-notch CPA and tax attorney. Peter even held his skills in high enough esteem that he kept Louis on as the team's personal finance specialist.
In 1984, Louis Tully is a resident of the Shandor Building at 55 Central Park West and is on the 22nd floor. Louis occupies 2202. He is mysteriously locked out of his apartment numerous times, unaware of the supernatural history of the building.
One night, Louis was hosting a party in honor of his fourth anniversary as an accountant. At the time the Terror Dogs Vinz Clortho (The Keymaster) and Zuul (The Gatekeeper) escaped and began to search for host bodies. Vinz found its way into Louis' bedroom. After Louis unknowingly tossed the coats of Ted and Annette Fleming onto Vinz, it disrupted the party and chased down Louis until he was cornered in Central Park outside the Tavern on the Green, after which the Terror Dog possessed him.
Louis, now inhabited by Vinz Clortho, runs around Central Park harassing random people in search of Zuul, The Gatekeeper. He bumps into a Coachman who gives him a hard time, growling at him as his eyes flared purplish-green. He later was picked up by the Cops, who in turn dropped him off at the Firehouse. Egon Spengler took some P.K.E. readings and took custody of him. Vinz introduced himself and his purpose to Egon Spengler and Janine Melnitz. Following Mr. Peck's visit and the resulting explosion, Louis escaped, staggering around amidst the chaos in New York City in search of Zuul until finally finding The Gatekeeper in Dana Barrett's blown up apartment. They kiss lustfully then head up to the rooftop where they consummate their demonic union, later transforming back into their natural Terror Dog forms. After the Ghostbusters battled Gozer, Louis was released from his possession as the Keymaster and returned to normal. Egon, Ray Stantz and Winston Zeddemore helped Louis get out of the charred remains of Vinz.
At some point between 1984 and 1989, Louis earned a law degree at night school and expanded his specialties as a tax attorney. On occasion, he would work on probate. In late 1989, at Peter's insistence, Louis reluctantly becomes the defense counsel for the Ghostbusters. Despite only being versed in Tax law, he won the case due to mitigating circumstances. After the Ghostbusters went back in business, Louis was part of their staff as personal accountant and tax attorney, even going so far as to appear in one of the TV ads. At one point, Louis catches Slimer eating his lunch and both flee in opposite directions screaming.
During the week of New Years Eve, Louis finally struck up the courage to ask her out on a date. Janine was busy with babysitting Oscar but asked him to come along. While babysitting with Janine at Peter's apartment, the two became closer and made out on the couch. Oscar was kidnapped. After Dana left to go to the museum, Louis went to the Parkview Psychiatric Hospital to rescue the Ghostbusters. He returned to the Firehouse and with Janine's help, suited up in one of Egon's Uniforms and then left by foot with a Proton Pack on. Underestimating the weight of the equipment, Louis quickly became tired. He was saved by the timely arrival of a city bus that Slimer had commandeered, patching up their incident earlier. Shortly upon his arrival at the museum, Louis starts blasting the Slime Shell covering it as Vigo became weakened from revelers' singing. Upon the defeat of Vigo, the slime shield dissipated, and the crowd hailed Louis as a hero even though he had little to do with the situation.
Ghostbusters: The Video Game Realistic VersionsEdit
Louis held onto Egon's coveralls as a memento of his experience during the Vigo incident, and hung up behind his desk in the lobby. He apparently switched the label from Spengler to Tully. In anticipation of the Ghostbusters offering franchising, Louis was tasked to scout locations around the USA, including Chicago, Los Angeles, and Cincinnati. During the start of the Thanksgiving 1991 holiday weekend, during the time when The Rookie was hired, Louis was not at work. He had not been feeling well and left work early, leaving a note on his desk informing the others. If the work piling up on his desk is any indication, Louis has been sick for several days, at least.
Secondary Canon HistoryEdit
Louis appears in seasons 5 and 6 and is portrayed as a wimpy and frugal accountant. He did use the Proton Pack a few times during his time on the show.

Legion Mini SeriesEdit
After Gozer's defeat, Louis became rich and famous. He made the covers of magazines like Digipocalypse, set off a geek chic fashion trend, became the spokesperson for Keymaster Cologne, and dated models. However, he still desired Dana and even secretly moved into the unit across from Dana in her new apartment. Louis still indulged in financial planning to a degree, and attempted to get the Ghostbusters into investing in a mutual fund. Six months later, Louis sponsored the Fireman's Ball and was its Guest of Honor. Once Michael Draverhaven was defeated, Louis propositioned Peter in his apartment elevator. He offered $1 million to stay away from Dana just so he could get a chance at her. Peter was shocked. Louis raised his offer to $2 million but Peter turned him down and went to see Dana.
Ghostbusters: The Video Game Stylized VersionsEdit
While at the Natural History Museum, Winston instructed Rookie to take a mental head count for Louis.  After Ivo Shandor was defeated, Peter revealed Louis had been scouting locations for new franchises and offered Rookie a choice of Chicago, Los Angeles, or Cincinnati.
At some point, Janine and Louis broke up. It also appears he no longer works for the Ghostbusters. Since then, he left New York.  Louis' law degree later influenced Winston to take up studying law, just in case the Ghostbusters went out of business again.

- Mentioned by Winston in Museum level and Peter at the end
- IDW Comics
- In the July 6, 1983 script, Louis Tully was a visiting conventioneer. 
- John Candy was originally going to portray Louis Tully and thus, molded to match his persona. Louis first appeared in the June draft as a fellow refugee of the creature which was to become Peter Venkman's interdimensional love interest. With a diet cola commercial, one creature turns into a beautiful woman while the other turns into a heavy-set man. Joe Medjuck notes Louis would have been similar to Candy's Johnny LaRue character from SCTV. Rick Moranis took on the role and added to the character, even improvising lines during the party scene.  
- In a deleted scene of the first movie, Louis seems to recollect the passionate kiss with Dana which she remembers vaguely, but refuses to entertain it and says, "No, Louis. No," as she walks away with Peter. The other Ghostbusters tell him there are other fish in the sea.
- In the Ghostbusters role-playing game, Louis is apparently the head of the business end of "Ghostbusters International" the franchise where roleplayers can sign up for. He is known to send player characters memos regarding the state of the franchise. He also prefers to be called "Lou."
- Louis owns or at least at one point in the past owned a pet hamster, even reading it bedtime stories as practice for taking care of children one day. He tends to re-write fairy tales to include financial and tax matters. This practice appears to have paid off as little Oscar Barrett seemed pretty at ease with Louis.
- When once asked if he lived alone, he replied his mother was his roommate. Until she moved to Florida.
- In a deleted scene and subsequent adaptations of Ghostbusters II, Louis went to his cousin Sherman Tully at Parkview to get the Ghostbusters released. 
- Rick Moranis is retired from acting.
- In the 10/8/2007 draft of Ghostbusters: The Video Game, Louis would have appeared in three cut-scenes.
- At the start of the game, in the lab area, Ray calls Louis away from his desk to try on a device made from a spaghetti strainer connected to an elaborate series of wires and electrodes set to 50% to keep burning or tissue damage to a minimum. They change their minds and decide to use the Rookie instead. Louis, unfazed, goes back to his desk. After the Psi Energy Pulse passes through the Firehouse and the guys muse there will be a spike in paranormal activity, Louis agrees it will be good for business. Janine and Louis later watch the Ghostbusters leave for the Sedgewick Hotel in pursuit of Slimer. 
- As the Ghostbusters prepare to return to the Sedgewick Hotel, Louis asks if warranty cards should be filled out. 
- As the Ghostbusters are about to shut down their Containment Unit to fight ghost army with ghost army, Louis worries this will expose them to all kinds of liability. 
- Rick Moranis came around towards the end of production of The Video Game and was okay with being involved with the game. It so happened that his head was modeled and ready to go but there wasn't any manpower left to rig him in animation because everyone was working on finishing the cinematics. 
- There was an idea of putting Louis in a fully body cast
- There was an idea of making the area where the Ghostbusters II No Ghost sign, miniature satellite dish, and Ecto 1-a doors are stored Louis' office and just have Louis stick his hand out and play some recorded lines.
- This is all likely why Tully was written out of the story as sick in Realistic Versions of The Video Game and out scouting locations for franchises in the Stylized Versions.
- In Ghostbusters Volume 2 Issue #4, when Ron Alexander sarcastically asks if there's a talking dog, Ray refers to Louis, who was possessed by Vinz Clortho.
- In Ghostbusters Volume 2 Issue #6, Egon Spengler and Roger Baugh enter a memory from New Year's Eve 1989 when Janine and Louis fooled around in Peter's apartment.

Harold and John had worked together in SCTV up in Canada and all of us worked in Stripes and only naturally he should be in this film. And John didn't understand this part. He kept coming back and saying well maybe I'll play him in German. He'll have a German accent and he'll have Rottweilers. I said you can't have dogs, we already have too much dog imagery in the movie. And he finally passed on the film. Rick Moranis, who had been sent the script by his agent, was waiting patiently in the wings and was very happy when John passed..."/Joe Medjuck says: "But we changed the character a lot. Rick really helped create this character."/Harold Ramis says: "He brought some fine speeches to this character."/Ivan Reitman says: "And I think he chose the wardrobe."
