Revealing mistake: During the ghost of Christmas present, Kermit is walking with tiny Tim on his shoulder and you can tell Kermit is walking on a spinning drum. Right before the camera pans away you can see Kermit's feet slide like he stopped walking but the road kept spinning. (00:55:00)
Continuity mistake: In the scene where the Beatles are in bed sleeping, and Ringo is getting pulled out of bed by the ring, he falls out of bed, and brings the blankets with him. In the next shot however, the bed clothes are back on his bed.
Factual error: One of Angel's lyrics (in "Today For You, Tomorrow For Me) refers to the movie "Thelma and Louise." Rent (the movie) is set in 1989-90. "Thelma and Louise" was released in 1991. This was caused when they did the move from Broadway to the screen. The stage show did not specify the year. So when they adapted the stage show to the movie, they didn't check the references. Plus it just sounds cool. (00:28:25)
Continuity mistake: Lady is put in her bed and the master leaves the kitchen but he goes back in and puts a newspaper on the floor and leaves again but Lady gets out of her bed so the master comes back once more and puts her back in her bed but the newspaper on the floor has vanished.
Continuity mistake: Polly Browne is in her dressing room with a picture of Tony Brockhurst on her mirror. She starts to sing and picks the picture off the mirror. As we see a close-up in her hands it is a totally different picture of Tony. As she puts it back, the photo has reverted back to the original.
Continuity mistake: The scene where Col. Hathi inspects his troops, he leans on his stick and it breaks. However, in the next scenes, the stick you see is sometimes broken and sometimes it is still complete.
Factual error: At the end of the 'Goodbye' the men all board a train which leaves along a track on a seaside pier. The shot changes from this stylised vision to a shot of an Edwardian Lady alone on a railway platform. In the background is a 1970s, ie. modern, diesel train.
Continuity mistake: Nellie is called into Captain Brackett's office one day. Later, one of the girls asks her "What did the old man want this morning?" However, the scene at night between Billis and Cable shows that a whole day and night must have passed in between these two scenes. Therefore the nurse should have asked "What did the old man want yesterday?"
Continuity mistake: When the Spanish singer is singing on in the club for the first time on her own, at the end of her song she stamps on her hat flattening it. In the next shot, the hat is back to normal.
Other mistake: In the opening scene on the airplane, one of the men tells Lt. Cable, "The captain wants to know if you'd like to sit up in the cockpit with him?" Buzz Adams, the "captain" referenced in this line, is only a lieutenant. Admittedly, "captain" is a standard aviation term for the pilot of an aircraft, but it would be unlikely to be used in this situation, since the term has a specific military meaning.
Factual error: After Berry and one of the Country Bears get in the bus to find the others, they show a scene with the bus going along a road and Berry leans out the window. Here you can see the side of the bus is spick 'n' span clean. Then, later, the bus is as dirty as it was when it left the shack, very noticeable at the start of the carwash scene.
Continuity mistake: In the gala scene, Zeppo explains that Groucho is always on time and will arrive at exactly ten o'clock. Everyone starts singing the first big musical number, "When the Clock on the Wall Strikes Ten." There is even a shot of a clock set to ten. In the middle of the song, the clock strikes... six.
