Continuity mistake: In the scene where Devlin meets Molly for the first time (outside the pub) the ARP sand and water buckets on the wall are in one position. When Molly leaves the scene, just before Devlin enters the pub, the sand and water buckets have changed position. (00:43:15 - 00:44:20)
Continuity mistake: When Kong is lying in the hold of the Tanker, Jessica Lange's character is leaning over looking at him when her scarf falls off. When it lands on Kongs chest, it appears to be the size of a (very) large dinner table cloth.
Continuity mistake: In the marching band scene, the band casts long shadows - then NO shadows - then long shadows again (repeatedly).
Continuity mistake: In the masked ball scene, St. Ives grabs a party goer and steals his mask which you then see him putting on. It is a gold mask without any markings that covers most of his face, but a few moments later when St. Ives dances with Flora, he is wearing a much smaller gold mask with black decorative markings.
Continuity mistake: When Cinderella is running away after losing her slipper, she lifts her skirt, and she is wearing only stockings. In the next scene when she is singing a reprise of "He Danced With Me", she starts dancing, and she is wearing her normal shoes.
