Blooper

During "La Vie Boheme", when everyone is shouting "Fight AIDS" Collins has disappeared from his spot beside the chalkboard, but he is there in the scene before and after.

The outside of the subway train the characters ride in is an R-40, yet the inside is an R-32.

During "Out Tonight", as Mimi is opening her windows, about to step onto her balcony, her sleeves are not rolled up. When she steps out in the next shot, both sleeves are rolled up to her elbows without her having time to roll them up.

Before "La Vie Boheme", when the characters meet up outside, Maureen and Angel go to hug, yet when the shot is taken back from afar, Mimi appears to hug Maureen and Angel stands there with arms crossed.

During the Tango Maureen sequence Mark's jacket keeps moving throughout the shots.

During "Today for U", when Angel goes up the wall and flips over, it's clearly a stunt double and not Wilson Jermaine Heredia.

In Today 4 U, Angel sings " Like Thelma and Louise did when they got the blues..." The scene takes place in 1989, more than a year before Thelma & Louise (1991) came out.

In "December 29, 1989," there is a picture of a New York City Police Officer with a dark blue uniform shirt. New York City Police Officers wore light blue uniform shirts at that time.

When Roger is sitting in the window the morning after Another Day, there is a Coke can sitting next to him, of a model from some time after 1990.

Although the film is set in 1989-1990, there is a clear shot of a mural that reads "In Memory of Celia Cruz" (1925-2003), who was very much alive at the time.

During "Out Tonight", in a long shot of Mimi walking down the street, a building at the left edge of the frame has a billboard for Cache Creek Resort Casino, which was built in 2004 in Northern California.

In the number 'Today 4 U' the drum beats that Angel does on the table and the piping don't align with the drum beats in the track.

During the riot, right before the shot of Benny struggling to leave, you can see a cameraman and his "hidden" camera, used to get the audience's reaction, filming to the far right.

The One Way signs shown in the movie have a triangular shape, those are only used by One Way signs in California, not New York where this movie takes place.

During "Finale B", Mark shows his film and there is footage of Angel singing during "Today 4 U". Mark was not filming during that scene.
