Corrected entry: During the Our Last Summer sequence, Bill sings "those crazy years, that was the time of (the) flower-power". But this doesn't make any sense in the chronology of the film. Clothing styles and comments about the Internet indicate that the film is set in the present day. Sophie is aged 20, which means that she would have been conceived in about 1988 - about 20 years after Flower Power. Bill's lines only make sense in the context of the original Abba song which was written around 1980.
Corrected entry: When Sophie is getting ready for her wedding, during the scene when Donna is painting her toe nails, Sophie's hair is down. In the next shot when her and her mom are looking at pictures and laughing, her hair is braided. Then Sophie is looking in the mirror in the next shot and her hair isn't braided.Jennifurball
Corrected entry: During the song "Take a chance on me," you see a bunch of people dancing on the crack in the courtyard. Yet when the water breaks through, there is nobody around it.
Corrected entry: When Sophie and Sky are singing/dancing on the beach, sky is holding a cigar. At one point when he makes to kiss Sophie, he appears to be burning her hair with the lit end of the cigar. And when he takes a puff in the next shot when standing on a rock, it is the wrong way round.
Corrected entry: In the early scenes, where the invitations are posted, the mail box is a French one - but the film is set in Greece.
Corrected entry: During the song "Mamma Mia!", when Donna is on the roof of the goat house, you can see that the surface she is standing on is stone or concrete with no gaps in it. But when the camera goes to the three fathers inside the goat house, there is light shining through the ceiling as though it were made of wooden panels. If there was stone on top of the wood, there would be no light coming through.Jennifer 1
Corrected entry: During the song "Slipping Through My Fingers", Sophie is walking out of the shower and has cut herself shaving. She then lies back on the bed and Donna puts a band-aid on the cut. Right after she does that, there's another shot of Sophie, who leans back, and at that point, her nipple is briefly visible peeking out from her towel.
Corrected entry: Based on cast lists from the Internet Broadway Database and the Internet Movie Database, not a single cast member from any Broadway production of "Mamma Mia!" appears in the movie.
