Trivia: In the last scene, when the choir sings at the church, the Blues Brothers can be seen on the background in exactly the same position as the church number in the Blues Brothers film.
Trivia: "Sister Act" is credited as being written by "Joseph Howard." He wasn't a real person. It was a pseudonym Paul Rudnick made up for the film since his script had been re-written so many times by so many different writers that it didn't resemble what he originally wrote. He settled on the name when "R. Chasuble" and "Goofy" were rejected as possible names.
