Trivia: The man who plays Todd the bartender at the swimming pool is Robin Williams' brother, Todd Williams.
Trivia: Adding to the 'carpe dentum' contribution, if you look at Pierce Brosnan when Mrs Doubtfire gets up from the table, he is moments away from bursting out laughing. According to the commentary track on the dvd, it was this reference to Dead Poets Society that tickled Brosnan but he managed to keep a straight face and so they didn't need to reshoot.
Trivia: In the scene when they are having dinner, and Mrs Doubtfire is fishing the teeth out of the wine glass, she says: "Carpe dentem - seize the teeth" This was a parody of "carpe diem - seize the day" from "Dead poets society". (Yes it's a well known Latin phrase, but the Robin Williams reference is the important bit).
Trivia: When Stu calls Daniel a loser at the swimming pool, Mrs. Doubtfire then picks up a lime and throws it at Stu, hitting him on the back of his head. Robin Williams managed to hit Pierce Brosnan on the third take and the lime you see was made of foam rubber. Mrs. Doubtfire then tells Stu it was a 'run-by fruiting' - this line was improvised by Williams.
Trivia: Robin was always trying to get Sally Field to laugh on the set. At one point he did voice imitations of scenes from "Smokey and The Bandit." All he got was a dead stare from Sally.
Trivia: Near the end, when they are in court and Robin Williams makes his emotional closing statement, it actually had to be re-shot because the first time he did it, it was apparently just too much, and the crew were just left speechless. The director decided that this was perhaps a bit too much to take and so they re-shot it.
Trivia: Near the beginning, the kids are watching something on TV with a man transforming another man's face. This is the second episode of the 1963 television show The Outer Limits, known as The Hundred Days of the Dragon. Part of the plot of this episode involves a man wearing a mask and makeup pretending to be someone else. That's the plot of Mrs. Doubtfire as well.
Trivia: The scene where Daniel takes his damaged mask of Mrs. Doubtfire to his brother was not in the original screenplay. The producers felt that a scene needed to be added in order to explain why Daniel needed to continue his charade as Mrs. Doubtfire. This scene was improvised on the spot.
Trivia: When Mrs Doubtfire accidentally sets herself on fire in the kitchen whilst preparing dinner for the family, the boiling water pot originally had a metal spoon in it. In one take, Robin Williams picked up the spoon and attempted to put out the fire with it, but the spoon was so hot that Williams ended up burning himself quite badly, so they re-shot the scene without a metal spoon and instead Mrs Doubtfire picked up a pot with potatoes in and dropped it on the kitchen floor.
Trivia: At the end of the scene where Mrs. Doubtfire helps Miranda choose a dress and gets invited to Bridges for her birthday, Mrs. Doubtfire is in a panic and turns around right into a wall after the conversation between the two ends. This could have been a deliberate mistake judging by Robin Williams' humor to add more character to the scene. Miranda reacts in a way that appears to be of legitimate concern. (01:28:57)
