Milquetoasty, nerdy, sexually frustrated accountant neighbor of cellist
Dana Barrett in
Ivan Reitman's "
Ghostbusters," written by
Dan Akroyd and
Harold Ramis. Louis Tully is eventually possessed by the
Keymaster,
Vinz Clortho, and seeks the
Gatekeeper, who has possessed
Dana Barrett. (Dana and Louis live in the art deco building designed by
Ivo Shandor, who started a secret society of
Gozer worshippers in the 1920s after witnessing the horrors of
World War I and deciding that society was too sick to survive. The building, according to
Dr. Raymond Stantz, is "like a giant antenna for psychokinetic energy".)
In
Ghostbusters II, Louis Tully begins a relationship with the Ghostbusters' secretary,
Janine Melnitz.
It should be noted that Louis Tully is the only character who is confirmed to have had sex with Dana Barrett in the Ghostbusters movies. (Dana denies at the end of "Ghostbusters" that she and Louis have had sex, but I believe that she is avoiding the truth.)
Rick Moranis plays Louis Tully. Originally this character was supposed to be played by
John Candy.
While possessed by Vinz Klortho, the Keymaster, he delivered this speech to
Dr. Egon Spengler and his secretary Janine Melnitz:
"Gozer the Traveller, he will come in one of the pre-chosen forms. During the rectification of the
Vuldrini he came as a large and moving
Torg (Torb?). Then, during the third reconciliation of the last of the
Mekretex supplicants, they chose a new form for him: that of a giant
Sloar! Many
Shubs and
Zuuls knew what it was to be roasted in the depths of the Sloar that day, I can tell you." (I humbly submit to you that in this moment Louis Tully is the father of
Garth Algar).
