Continuity mistake: In the pool scene where Mrs. Doubtfire picks up and throws a lime at the back of Stu's head, when Stu walks away and the camera goes back to Mrs. Doubtfire at the bar, the lime that she threw is still on the top of the stack of fruit.
Continuity mistake: At the end when the children learn that their dad is their new baby sitter, look at Chris' tassels on his coat from when they get to door to when Daniel says 'Go get your stuff' and he runs up stairs - between shots, his tassels are both hanging down, then hanging to the right, then hanging down etc. indicating this scene was shot at least twice.
Continuity mistake: 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.
Other mistake: When Chris sees Mrs. Doubtfire in the bathroom she is standing up and peeing, in costume. All the scenes where Daniel is putting the costume on shows that the fat suit is a body suit, in one piece, and there's no opening in the front. So he shouldn't have been able to pee without taking off the whole suit.
Continuity mistake: In the scene in the kitchen while Daniel is looking for a face, his robe is not closed completely at the top, but as soon as Mrs. Stelner enters, the robe is done all the way up and quite tightly. After the face cream in the coffee, Mrs. Doubtfire leaves but quickly sticks her head back in the kitchen and her robe is again loose at the top.
Audio problem: During the final court case scene at the end of the film, Miranda's lawyer turns to her and says, 'Congratulations'. The lawyer's head is turned away from our view slightly, but you can see that she doesn't move her mouth. It does move about a second after 'Congratulations' is said, but it does not move long enough for the lawyer to have actually said 'Congratulations'.
Continuity mistake: In the scene where Mrs. Selner inspects Daniel's apartment after meeting Mrs. Doubtfire, Daniel is tidying up the place a bit. He picks up some articles of clothing, and then goes off to get his "sister". Before leaving down the hall, his pile of clothing is completely covered by a blue skirt or dress. But the next shot shows Daniel with a white article of clothing on top.
Continuity mistake: When Daniel is in the bathtub, speaking in a German accent while on the phone with Miranda, he asks her how many children she has. At this point Daniel's chest is clean. It then cuts to Miranda who says, "I have two girls and a boy." In the next shot, however, Daniel's chest is suddenly covered in bubbles.
Continuity mistake: When Chris and Lydia discover that Mrs. Doubtfire is really their father, he explains Uncle Frank's and Aunt Jack's part in it. When it cuts back to Lydia, she has a long length of hair down the front of her right shoulder, but in the next shot, when she says, "It's really you in there," the hair is suddenly behind her shoulder.
