Continuity mistake: In the beginning, when Mr. Banks is calling the police and talking to his wife at the same time, the phone cord changes position between shots.

Continuity mistake: When Mary Poppins just starts to sing "Feed the Birds", she sings "The little old bird woman comes" but if you look very closely at the end of this shot, you can see that her mouth does not finish the word "comes" (her mouth stops at come).

Revealing mistake: There is a certain point in the song "Step In Time" (I believe it is when we see a couple of men switching their feet on the top of a chimney) where against the sky you can see where a wall and ceiling meet. This is because the scene was shot indoors.

Revealing mistake: When Mary Poppins has the robin on her finger, just after the outside shot where the robin does his whistle bit, you can see the cables used to operate the bird on the back of her hand while she turns away from the window.

Revealing mistake: After Michael and Jane have been sucked into the chimney and then pop out, Mary Poppins pops out a short time afterward. When she does so, a dark, obvious cable can be seen supporting her.
