“Hey, Malkovich! Think fast!”
The scene: John has just had a pretty angry confrontation with Craig Schwartz on the side of the road. “Being John Malkovich” was released just before the turn of the century. The movie was renowned for satirically capturing the real John Malkovich himself.
When filming, a drunk cast member throws a can at Malkovich’s head, which inspired this unscripted line. This was an extra that had no lines. But, instead of being kicked off, the directors thought it was so funny that they kept it in the final cut and gave them a pay raise.
Caddyshack
"What an incredible Cinderella story!" The scene: The main character Carl Speckler (who was played by Bill Murray) is ‘lopping the heads off bedded tulips’ when he practices his golf swing. “Caddyshack” was first released in the early 80s and featured some big names like Rodney Dangerfield, Chevy Chase and of course the famed Bill Murray.
One of the best comedy actors in film history, Murray, is known for his one-liners. In this scene, he was so focused on beheading the flowers that it made for one of the funniest moments in cinema history. The Cinderella reference he makes has basically become a popular saying until this day, thanks to Murray's brilliant improvisation.
Blade Runner
"I've seen things you people wouldn't believe. Attack ships on fire off the shoulder of Orion. I watched C-beams glitter in the dark near the Tannhäuser Gate. All those moments will be lost in time, like tears in rain. Time to die." The scene: Roy Batty saved Rick Deckard’s life, but then ultimately caused his own death. He gives his last words in the rain about to die.
Rutger Hauer improvised lines about his short life that were incredibly meaningful and downright poetic. It is almost difficult to believe he came up with it on the spot, but he did. He didn’t believe the original script correlated to his character, so he made the lines up, surprising everyone on set.
Shaun Of The Dead
"Cockocidal maniac."
The scene: Ed and Shaun are having a drink. Ed is trying to get Shaun to forget about his troubles. “Shaun of the Dead” was an absolute riot when it came out in 2004. It somehow managed to blend horror and comedy into one big, beautiful British mix.
And it doesn’t really matter how many times you have watched it - it just never gets old. Nick Frost made up his whole backstory for this scene, and it paid off! No one can ignore how hilarious his lines were, and that is why they are still remembered to this day.
Jaws
"You're gonna need a bigger boat."
The scene: Martin Brody and Quint are standing on the boat, trying to catch a large shark. They notice that the shark is way larger than they imagined. “Jaws” is a realistically terrifying thriller that came out almost 5 decades ago.
This line was actually an inside joke within the cast and production crew, so when Roy uttered this line in the scene (which was completely unscripted), the directors thought it was way too funny not to include. It just fit the scene so perfectly at the time that they couldn’t not include it in the final cut of the film.
