Continuity: In the Souper Trouper scene, when we see Dona, Tanya and Rosie raising their left hands, we see that Rosie is just behind Dona's sleeve. However, in the next shot, in which we only see Dona, we can't see Rosie or her shadow at all.

Continuity: In the shot in the bathroom, Tanya has a small diamond necklace but in the next shot in the bedroom the diamond appears larger.

Character mistake: 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.

Continuity: 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.

Continuity: 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: During "Money, Money, Money" Donna walks into the kitchen and all the staff are sitting at the table. They hurriedly get up and start working, and a newspaper is left right beside the large fish on the table. When the shot goes back with the table visible, the newspaper has gone.

Continuity: 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.

Visible crew/equipment: When singing Dancing Queen an extra is seen falling off a ladder. If you look at the front of his shirt, a safety cable can be seen.

Continuity: When Tanya first arrives, at the end of the song, her arms constantly change place between shots.

Continuity: When singing Dancing Queen the hair dryer changes from silver to green instantly.

Continuity: When Tanya and Rosie arrive at the island, they get off the boat and walk up the pier. They break into song with Donna (who is walking towards them) but as the shot keeps changing, the two old men standing on the pier disappear and re-appear every time the camera changes.

Continuity: Soon after arriving, Tanya and Rosie are at a bar and suddenly Donna comes out in tears. Tanya is just receiving a cocktail from Pepper, the bartender. Rosie and Tanya then hurry after Donna - and during the rest of this scene, the amount of drink in Tanya's cocktail keeps lowering then rising.

Continuity: 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.

Continuity: At the chapel, Sam has just proposed to Donna. She says she's not a bigamist. Sam says neither is he and that he has loved Donna for the past 21 years. To his right stands Sophie, who after hearing Sam say this, is all choked up and looks like she's about to burst into tears of joy. Immediately after you see this expression we see Donna very briefly (one or two seconds). When the shot goes back onto Sam and Sophie, Sophie has a huge grin on her face. Nothing is said by Donna or Sam in this extremely brief period of time that would justify her instantaneous change of expression.

Continuity: When Meryl Streep closes the bedroom door in the scene right before "Dancing Queen", you see Julie Walthers' reflection in the mirror next to her, hands on her hips. In the next shot Streep turns to face Walthers, who now suddenly hasn't got her hands on her hips anymore.

Continuity: When singing Mama Mia the first time, the position of the mum's arms are constantly changing between shots.

Continuity: 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.

Continuity: 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.

Continuity: When Tanya and Rosie sit down on the boat on the way to the island, as they sit down Tanya has her hands in her lap. In the next shot they're up by her neck.

Visible crew/equipment: At the end of a song near the end, (can't remember which one) the stage lights and a light screen can be seen in the champagne glasses of the guests.
