Continuity mistake: Polly Browne is in her dressing room with a picture of Tony Brockhurst on her mirror. She starts to sing and picks the picture off the mirror. As we see a close-up in her hands it is a totally different picture of Tony. As she puts it back, the photo has reverted back to the original.
Visible crew/equipment: When Maude pulls the banjo out of a cabinet, you see the reflection of crew and lights.
Continuity mistake: When the farmer threatens Henry VIII with a fork after he catches him in the barn with his daughter, you can see that Henry is holding on the fork and it is well away from his body, but in the next shot the fork is pointing near Henry's face.
