What are some of the improv moments that were left in movies that you like? This is something of an interest of mine, I love good improvs. We all know the famous ones, like "You talkin to me?" and "You're going to need a bigger boat." What are some of the less known ones? Off the top of my head:

"Winter's Bone," the scene with the Army recruiter. They hired a real life Army recruiter and gave him no lines. He was told to just talk to Jennifer like he would any kid who sat down in front of him.

"Cape Fear" remake. The auditorium scene. I've read the whole sequence with DeNiro and Juliette Lewis was totally ad libbed and done in one take.

"A Few Good Men." Tom Cruise's little Jack impersonation, "He eats breakfast three hundred yards from people trained to kill him." Tom wasn't supposed to say that line with a Jack-ism.

"Se7en," Lee Ermey, answering a ringing phone. "This isn't even my desk." Slam

Others?

Dustin Hoffman, MIDNIGHT COWBOY: "I'm walkin' here, I'm walkin'!"

The scene in Captain Phillips when he's being examined in the infirmary.

Best in Show when Christopher Guest is talking to his dog.

I love that scene. I know Tom Hanks has a reputation for being vanilla (which I do t necessarily agree with) but that’s scene in particular is one of the most well acted scenes I’ve ever watched!

Harrison Ford's "Situation normal, we're all fine, how are you?" scene in Star Wars.

Harrison Ford with the sword man in Raiders

Not a line, but the unplanned spit-take on De Niro By Walken in Deer Hunter

OMG can you people read? I said lesser known ones. Everyone knows about Strangelove and "I know."

The cape fear one is not true. It very obviously was not done in one take. The actors may have worked it out without a script by workshoping it together, but you can't improvise a whole scene like that on the spot.

Also his line, "It's not the years, it's the mileage".

... but if people like Stragelove and "I Know" then they're answering your question

with your second question being:
sooo yeah, clearly people can read you just have to make sure you remember what you wrote

Also, not everyone has seen every movie being discussed, popular or otherwise.

Does this count?

Not any more. It's too well-known, dammit!

You seem nice.

Great one. He even comes out of character, listen to his voice it’s all Hoffman there.

Plus, people often skip the first post if the thread title seems to give a clear indication of what the poster is looking for.

love Tom Hanks, probably one of the few celebrities I would like to actually shake his hand

I love when OPs go apeshit in their own threads
