Factual error: At the very end of the movie, the Pope gives the nuns a standing ovation. The other people seated in the box with him should have immediately risen at this time. Instead, the man seated to his left looks up at him, seeing that the pontiff has stood, but makes no movement to join him on his feet.DavidK93
Continuity mistake: When Whoopi first takes over the choir, she asks the sisters to stand according to their singing voices. She asks where the sopranos are, and several women on opposite corners of the grouping raise their hands. She asks them to all move over to the left group, but only one of the two women on the right side actually does so.DavidK93
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.Bishop73
Reverend Mother: Girl groups? Boogie-Woogie on the piano? What were you thinking?
Dolores: I was thinking more like Vegas, you know? Get some butts in the seats.
Question: When the nuns perform for the pope at the end of the film, the pope is seated in the balcony. I was wondering if this would actually happen in real life. Wouldn't the pope be down at the front of the church to celebrate the Mass? I suppose he could have gone up to the balcony just for the singing but that doesn't make much sense.
