In the scene where Sean starts talking about his dead wife and her farting antics the lines were ad-libbed by Robin Williams, which is why Matt Damon is laughing so hard. The scene took everyone by surprise. According to Damon in the DVD commentary, this caused the cameraman to laugh so hard that the camera can be seen moving up and down slightly.
Here’s to Robin Williams, the man who has sparked more fire in my funny bone than most. No matter the role, Williams’ talent radiated on-screen, warming my heart whilst making milk come out of my nose at the same time. He was the star of my favorite childhood movies: Jumanji, Hook, Flubber, and Mrs. Doubtfire among being an inspiration in my all-time favorite film Dead Poet’s Society. Heck, this man could even take on a different role in One Hour Photo and still stun the socks off of me.
I am deeply saddened by the news of this legend’s passing and am marathoning my favorites in his honor. No one ever made me laugh the way this man did and I don’t think anyone ever will. Rest in peace, Robin.
