Continuity mistake: Donna, Tanya and Rosie are singing Super Trouper for Sophie's Hen Party - when they get to the end of the song and all 3 ladies put their hands one of top of each other (whilst they are singing 'Like I always do') and then lift them above their heads. Rosie's hand has changed, in the first shot it is her right and in the second her left hand. (00:48:40)
Continuity mistake: When they are singing Does Your Mother Know You're Out, a man is seen getting out of water and then lying in the sand. When he stands up no sand sticks to him, which it should. (01:09:00)
Continuity mistake: Just before the song "Does Your Mother Know" on the beach, the items on the bar change their position during the scene, from shot to shot. For instance, the bucket of ice, Tanya's bag and drink, etc. (01:09:25)
Continuity mistake: When Tanya is singing "Does Your Mother Know", she walks away from the bar and goes out to the beach to join the crowd of men who are dancing. As she's walking, there's a side shot of her, and in the background you see an extra with a towel around her waist wearing red wayfarer sunglasses. But then there's a face-on shot of Tanya, and the extra's sunglasses have disappeared. (01:10:30)
Continuity mistake: During the last half of the movie Donna wears a red sweeping shawl over her shoulders, with her outfit for Sophie's wedding. Many times the position of the shawl is not consistent during shots - most noticeable after she walks Sophie down the aisle, then sits down. (01:21:05)
Continuity mistake: During the wedding scene, all three of Sophie's possible fathers stand up and gather behind her on the aisle. In one closeup shot Sophie turns around to say something to Sam - in this shot the right part of her hair is behind her right shoulder. In the next shot as she is turning around back to face the priest, her hair is suddenly neatly in front of her right shoulder. (01:25:50)
Visible crew/equipment: When Donna is telling Tanya about Sophie's dad arriving, stage lights can be seen in Donna's glass.
Continuity mistake: When Sophie is finally dressed for her wedding, the gauzey material is predominately over her right shoulder/breast. Next shot it is over her left. When she gets on the donkey, it is completely off her right side and her bra shows.
Revealing mistake: After Sophie faints at her bachelorette party, during the next scene it cuts back and forth between shots taking place in two rooms - Donna walking into Tanya and Rosie's room, then Sophie walking into Ali and Lisa's room, and both rooms have the very same cracks and stains on the walls revealing it was filmed in the same room, but with different furniture.
Continuity mistake: When Rosie and Tanya follow Donna into the bathroom, during the "Chiquitita" scene the flower pot on the windowsill moves back and forth from the left side to the right side.
Factual error: When you first see Sam he is supposed to be in America, but when you see out of the window as he is leaving, you can see the Gherkin building in London. He is actually in the Lloyd's Building, but to add to the illusion of being in America, he is picked up by a Yellow Cab.
Continuity mistake: During 'Winner Takes it All', at the start of the song, Donna has her hands up near her chest, in the next shot they are down by her side.
Continuity mistake: In the Super Trouper scene, when we see Donna, Tanya and Rosie raising their left hands, we see that Rosie is just behind Donna's sleeve. However, in the next shot, in which we only see Donna, we can't see Rosie or her shadow at all.
Continuity mistake: When Donna is dancing to "Dancing Queen," her hair is all messed up. But in the next shot, her hair is not messed up.
Continuity mistake: During Dancing Queen Donna is jumping on the bed. Between the camera angles, her position keeps changing.
Continuity mistake: At the end of Voulez Vous, the people pick up Sophie. In one shot her hair falls down to her shoulders, camera cuts and it falls back down again.
Continuity mistake: When Sky is on the beach with Sophie, his arms are constantly changing place depending on the shot. This is not due to dancing.
Continuity mistake: When singing Mama Mia the first time, the position of the mum's arms are constantly changing between shots.
Continuity mistake: When Tanya first arrives, at the end of the song, her arms constantly change place between shots.
Audio problem: Sophie and her boyfriend sing at the beach, he says he likes to smoke and pronounces the word "true" with the camera facing him. Right afterwards there's a side shot and music is heard with no lyrics, but he is mouthing as if singing. Then back to a front shot and now he sings and mouths.
Chosen answer: Meryl Streep and Pierce Brosnan got married because they loved each other and had done for many years. The daughter changed her mind about getting married because she realised what really mattered to her and that seeing the world while they were young and free wasn't such a bad idea after all, that she didn't need to get married and hang around for her mother's sake.
