Visible crew/equipment: When Mrs. Doubtfire is cooking in the kitchen and sets her fake boobs on fire and hits them with the pan lids to put them out you can see the camera crew in the reflection of one of the pan lids.

Continuity: In the scene where the social worker is at Mr. Hillard's house and his so-called "sister" (Mrs. Doubtfire) is trying to find a face in the kitchen, one moment the wig is all messed up from being caught on the door. In the next scene, where she is looking in the fridge to find the face, her wig is perfectly in place.
