Visible crew/equipment: When Mrs. Doubtfire is cooking in the kitchen, sets her fake breasts on fire, then 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 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.
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 Mrs. Doubtfire and the family go to the pool to meet with Stu, you see the same two women in bikinis cross in front of the gate a few times in less than a minute, always going in the same direction.
Continuity mistake: In the scene at the pool, when Pierce Brosnan dives into the pool and comes out look at his hairline, and look at it again in the next shot after his hair stylist intervened.
Visible crew/equipment: In the scene where Mrs. Doubtfire and the kids are on a trolley, as the trolley passes you can see the crew in the trolley window.
Revealing mistake: When the Hillards are at the pool, we see Stu, with his hairy chest, on the diving board. When the shot zooms out, we see a guy with no hair on his chest, who is obviously the stunt double.
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: 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.
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.
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: Daniel (disguised as Mrs Doubtfire) is cooking and knocks the cap of the pepperpot into the frying pan. In the following shot, Daniel hasn't removed the cap, but it's not there any more.
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 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.
Other mistake: At the start of the film we see Gloria Chaney, the Hillards' neighbour, drop a rabbit at her feet and then shout 'shoo' at it whilst pushing it with a brush. If she had it in her hands, why didn't she just drop it outside of her garden, instead of at her feet, making her have to push it to get it out of her garden?
Character mistake: When Mrs. Doubtfire gets her own TV show at the end, she asks the puppet if he knows anything about England. The reply is, "I only know that it's an island", which is not true. Britain is an island, not England.
Continuity mistake: In the restaurant scene when Daniel puts the cayenne pepper on the jambalaya, Stu takes a shrimp and starts chewing it before he chokes on it. When Daniel comes and performs the Heimlich maneuver on him and the shrimp is coughed out, it's whole and unchewed.
Continuity mistake: When Mrs Doubtfire is pouring the cayenne pepper into Stu's dish of jambalaya, you can see that the container has nothing on the side, but when Mrs Doubtfire has finished, a label has suddenly appeared.
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 (dressed as Mrs Doubtfire) is at the pool bar drinking, the bartender is wearing a black suit jacket. In the next scene, he is wearing a white suit jacket.
Continuity mistake: In the scene where Daniel and his kids are having dinner, when he's 'domesticized', the first pan shot is mirrored, because his daughter is looking to her left to congratulate him, but in the next shot and all the ones after that, he would be on her right, and the table would be flipped.
Continuity mistake: When Mrs. Doubtfire and Miranda are talking in the kitchen, Miranda's necklace' beads are crooked. In the next shot after Mrs.Doubtfire is seen, Miranda's necklace is astoundingly perfect.
Continuity mistake: When Harvey Feirstein's character is talking on the telephone to his mother about Daniel's divorce, he says "I love you, too." You then hear her say "I love you" afterward.
Continuity mistake: In the restaurant scene, just after Miranda takes Natalie to the bathroom, Lydia picks up her menu and opens it just a crack. Then Mrs. Doubtfire starts talking and the camera cuts to a closer shot, and the menu is suddenly all the way open.
