Best ad-libs in movies.

He's great in that movie. The way he goes from macho gung-ho bad ass Marine to blubbering idiot and then going out in a blaze of glory is alone worth watching the movie for.

 

Wasn't Robert Downey, Jr.'s Tony Stark announcing "I am Iron-Man" an ad-lib?

 

Are you certain this was an ab-lib?

There is very little in the 'Flying Circus' tv series or any of the Python films that is ab-libbed.

Can't help but think of Bullets Over Broadway - the scene when Jennifer Tilly (Olive) is rehearsing with Chazz Palminteri (Cheech). Tilly adds the word "Ha" and Palminteri says she can't do that.... One of the funniest scenes in the movie.



Olive : In some way you're trying to relive it and in the process of reliving it, correct it. As if that were possible. HA.

Cheech : It don't say "ha."

Olive : I know it don't say "ha," I added that.

Cheech : Are you allowed to do that? I don't think you're allowed to do that.

Olive : We're allowed to add things. It's called ad-libbing.

Cheech : Well, I think the whole thing stinks.

Olive : Well, I think you're a degenerate zombie so shut up and read.

Cheech : You shut up.

Olive : You shut up and read.

Cheech : You're lucky you're Nick's girl.

Olive : You're lucky you're an idiot.

 

Groundhog Day

In the penultimate encounter between Connors and annoying insurance salesman Ned Ryerson, Bill Murray was ad-libbing when he tells Ned, "I don't know where you're headed, but can you call in sick?" and causes Ned to run away.

 

My fav are all of the ones that Bill Paxton came up with in "Aliens".

 

in one of the "Road to...." movies, a camel spat in Bob Hope's face, and Bing Crosby immediately patted the camel on the head and said "good girl."

 

That happened because a real-life New York cabbie ran the barricade that had been put up on the street for shooting the scene.

 

"Mein Fuhrer, I can walk!"

The cuckoo clock speech from The Third Man.

 

The great lines strewn throughout A Hard Day's Night that weren't actually in the script -- which are which is the challenge.

Some sources say "Turn left at Greenland" was one of them.

 

Jimmy Stewart's reaction was great too.

 

I have seen that quote attributed to both John and Ringo in real life and reused in the movie.

 

Was just about to post this when I saw the thread had come up again. The Taxi Driver script only said something like “Bickle talks to himself in the mirror”, and DeNiro improvised a bunch of different dialogue with the cameras rolling.
