Overview
Thank God It's Friday is a 1978 American musical-comedy film directed by Robert Klane and produced by Motown Productions and Casablanca FilmWorks for Columbia Pictures. Produced at the height of the disco craze, the film features The Commodores performing "Too Hot ta Trot", and Donna Summer performing "Last Dance", which won the Academy Award for Best Original Song in 1978. The film features an early performance by Jeff Goldblum and the first major screen appearance by Debra Winger. The film also features Terri Nunn, who later achieved fame in the 1980s new wave group Berlin. This was one of several Columbia Pictures films in which the studio's "Torch Lady" came to life in the opening credits, showing off her moves for a few seconds before the start of the film.
Plot
Thank God It's Friday tells several intertwining stories of the patrons and staff of the fictional Los Angeles disco The Zoo over the course of a single Friday evening. These people include:
Tony Di Marco – owner of The Zoo. Lecherous and promiscuous, he's inordinately fond of his 1974 Porsche 911 Carrera.
Bobby Speed – the club's DJ, who's broadcasting his first live show from the club.
Frannie and Jeannie – two high school friends who want to win The Zoo's dance contest to buy KISS concert tickets.
Carl and Ken – hopelessly near-sighted shlub looking for a casual liaison, and his friend looking for a girlfriend.
Dave and Sue – a young married couple celebrating their fifth wedding anniversary.
Jackie – dental hygienist by day, drugged-out disco freak and Zoo regular by night.
Jennifer and Maddy – the new girl in town taken to the disco by her know-it-all friend who's not as sophisticated as she thinks she is.
Nicole Sims – an aspiring disco singer.
Marv Gomez – a self-described "leatherman" who lives to dance.
Malcolm Floyd – the roadie for The Commodores, responsible for delivering their instruments to the club by midnight.
Gus and Shirley – a mismatched couple on a blind date.
Sue insists that her uptight accountant husband Dave take her to the disco. On a bet with Bobby, Tony tries to pick up Sue. Dave is drugged and renamed "Babbakazoo" by Jackie, and makes a fool of himself. Carl and Ken are repeatedly thwarted in their attempts to meet girls. Frannie and Jeannie trick Marv into helping them sneak into the disco after several failed attempts at gaining entry. Jennifer tries to meet a guy, but Maddy vetoes each of the guys that Jennifer is attracted to.
