6/15. Robin Williams says the word “dear” 101 times throughout the film. Sometimes he says it clearly, and sometimes it’s more of a mumble. You have to listen very closely to hear all 101.
7/15. Director Christopher Columbus always had two to three cameras surrounding Robin Williams. This was because Williams was famous for spontaneously improvising and the camera crew never knew what he would do next.
8/15. While the movie was being filmed, Sally Field was going through a breakup with Burt Reynolds. Not only that, but Robin Williams would later go on to divorce his wife and marry his nanny (as opposed to divorcing his wife and becoming the nanny in the film).
9/15. Tim Allen was originally offered the role of Daniel Hillard/Mrs. Doubtfire but turned it down. He was also offered the role of Stu Denmeyer, but the role ended up going to Pierce Brosnan instead.
10/15. When Mrs. Doubtfire’s teeth fall into a wine glass and she proceeds to fish them out she says, “Carpe Dentum...seize the teeth.” This was a reference to Dead Poets Society in which Robin Williams famously says, “Carpe Diem...seize the day” to his students.
