Continuity mistake: When the Monkees (excluding David) and Ludlow come out of the cupboard that they hid in when Wendy Forsythe came to visit, you can see some items in there on shelves and neatly stacked. When David (as Ludlow) and Michael accidentally open the door a bit later (thinking they're going into a different room), they get covered in the items as soon as they open the door. Plus some of the items that fall on them were not even in there before.

Continuity mistake: In the karate dance number there is a girl in a red outfit behind Mike on the floor. She must change her position at least four times in ten seconds - she can be seen moving and laughing with the girl beside her on the floor.
Revealing mistake: When the female spy is taking the film off Mike who is out cold on the floor, the dancers can be seen working on the dance steps in the background. After all of the dancers have knocked themselves out they can be seen moving and laughing.
