Continuity: Towards the beginning of "Take Me or Leave Me", notice when Mark and Mimi walk into the background. In the next shot when you see the parents, you can see how close Mark is to them (his shoulder is in the frame). When they cut back to Maureen and Joanne, Mark is a lot further away from the parents. This is also mentioned in the commentary.
Continuity: When Collins introduced Angel to Roger and Mark, Angel holds out his hands with money in both hands. He then gives his right hand money to Roger yet in the front angle of him giving the second money to Mark, he gives Mark money from his right hand again. He wouldn't have had enough time to switch the money from hand to hand.
Other: At the very beginning, when the lights rise above the cast you can see they're all equally spaced out and the light has the same brightness for each character. At the end of the song, the camera shoots to the back filming everyone from behind, note Mark, he's crammed in the corner next to Angel with out the same amount of space originally he started with and his light is very dim compared to the seven others.
