Goofs

After Deloris witnesses the murder, she flees to the Reno PD and explains to the detective everything that Vince and his henchmen said to each other and to the victim right before the trigger was pulled, even describing the scene visually. However, when Deloris walked in on the murder, she actually opened the door a fraction of a second before the trigger was pulled, and had been talking to herself until the moment she turned the doorknob, so there is no way she could have heard or seen the preceding conversation that she reported to the police.

When Sister Mary Roberts gives Sister Mary Clarence the clock to help her wake up in the morning, you see Sister Mary Clarence's hand reach out for clock. In the next shot, Mary Clarence's hand reaches out for the clock again.

During the credits at the end of the movie, the spelling of Deloris's name rotates between Delores and Deloris on the magazine covers. The first two magazines (People and Newsweek) show "Delores", while the second two (Time and the National Enquirer) show "Deloris".

During "Hail Holy Queen", the nun sitting directly behind Mother Superior changes.

In the dressing room, Deloris refers to Vince as Mr. LaRocca, pronouncing his name "la ROE ca", but then refers to Vince's wife, pronouncing her name Connie "la RAH ca" as it is pronounced the rest of the film.

The order Deloris joins is stated to be a Carmelite order. Carmelite nuns are devoted to contemplation and prayer and do not typically engage in the type of community activities Deloris introduces in the film. It's not a matter of the nuns simply being too sheltered and naive to get involved with the world, but that they would have joined the convent with the understanding that this was not the sort of order that participated in secular outreach.

When Deloris was singing in the nightclub she had two back-up singers, but the back-up chords had three notes. Deloris was singing the solo, so that would be impossible.

Lt. Southner deduces that Lt. Tate is the leak and proceeds to punch him for it. He never saw Tate's phone call to Vince, so him being in possession of the receipts would not be enough evidence to arrest him.

Lt. Southner, as well as Vince's wife, see a news story about Deloris's convent. However, Reno and San Francisco are three hours apart, and that was a local human interest story. It would not have been broadcast to a city that far away in another state.

Lt. Southner promises a court date within two months, and later takes credit for moving the date up. First, it is very unusual for a felony trial (such as murder) to go to trial in less then a year, and it would require a Grand Jury indictment first. Secondly, said indictments and resets of court dates are not done by the police, but by prosecutors.

In the final song you hear can string instruments, but there is only a piano on the stage.

However, in live performances, many musical acts use backing tracks to fill in extra sounds.

When Sister Mary Roberts gives Sister Mary Clarence the clock to help her wake up in the morning, she says "I set the clock for 5:00," but the clock is really set for 7:00. This is probably because the film makers flipped or mirrored the image in that scene.

The opening scene shows young Deloris (Isis Carmen Jones) writing on the blackboard with her right hand. Whoopi Goldberg is left-handed.

However, in the old days, it was not uncommon for Catholic schools to force their left-handed students to write right-handed, as left-handedness was thought to be a deviation associated with the Devil that needed correcting.

When Deloris is invited to sort out the choir, she asks for sopranos, altos and bass singers. Women do not sing bass. Women's vocal singing range is soprano, mezzo-soprano and alto (contralto).

However, as Deloris has no known background in formal choral singing, there would be no reason for her to know this. Most professional singers have never heard the terms "mezzo-soprano" or "contralto". **Professional soprano with 30+ year career here-the different vocal parts are one of the first thing singers learn, so a singer who considers themself professional absolutely would know about them. Women do not sing bass, it's true, but female singers can follow a bass line, singing an octave down. Presumably, this is what she wants them to do.**

In the trailer for the film when Deloris walks in on the murder, a silenced pistol sound is heard. While, in the film during the same scene a gunshot sound is heard.

However, as film trailers are not considered part of the movie itself, this is NOT a Goof per IMDb guidelines.

Toward the end, as the nuns are looking out of the airplane window at Reno, it is quite obvious that they are merely looking at a string of Christmas lights.

When Sister Mary Clarence/Deloris is escaping from Joey and Willy, towards the end of the film, she is shot at. We hear the shot but, although the pistol is on screen at the same time, we don't see it being fired.

When Sister Mary Clarence is running through the kitchen to escape from Joey and Willy, they shoot at her as she starts up the stairs. Approximately one second elapses between the shot and the ricochet off the stair railing. In reality, at the distance the shot was fired, the ricochet would have been almost instantaneous.

During the first choir performance under Deloris, when the choir starts the second, more modern half of the song, the nuns start clapping. There are a lot of off-beat claps that can be seen, but not heard.

When Sister Mary Clarence/Deloris is meeting with the Mother Superior in her office right after the first choir performance in which she is choir mistress, a crewmember's hand can be seen trying to get the pigeons to stay on the window sill.

Mother Superior somehow forgets Mary Clarence is not a real nun. She feels threatened by a new nun and even tries to abdicate because she feels old-fashioned, as if Mary Clarence was a real example of today's church. Even when they talk in a room with nobody else to hear them (they couldn't have known about eavesdropping sisters behind the door), Mother Superior seems to be not aware that Mary Clarence is not a real newcomer to the convent.

In the first scene, young Deloris's teacher asks her to write the names of all the apostles on the blackboard, alphabetically. Deloris writes "John, Paul, Peter, Elvis." Until she writes "Elvis" the teacher is nodding in approval. Two things are wrong with this. First, Paul (though considered an apostle in a different context) is not one of the original twelve apostles. Second, when the apostles are written alphabetically, "Andrew" is the first. Any Catholic school teacher would have corrected her long before she added "Elvis" to the list.

Vince 's lawyer says he can't control the length of the police interrogation. He could on fact have terminated the interview at any time. Furthermore, any good lawyer would have told Vince not to go in for questioning in the first place.
