12 Unscripted Movie Lines That Became Classics

It's a given that actors speak the dialogue written in the script, but that's not always the case. Some of our most memorable movie lines were not in the script. They were ad-libbed by the actor and were so great they were kept in the movie. And many of them became classics. Here are some of those now classic lines of unscripted movie dialogue.

Casablanca (1942)

"Here's looking at you, kid."

Humphrey Bogart first said this line while teaching Ingrid Bergman how to play poker between takes. The phrase came out spontaneously during one of the Paris flashback scenes and became a recurring line in the movie, most memorably near the end.

Midnight Cowboy (1969)

"I'm walkin' here!"

Dustin Hoffman was genuinely angry when a taxi ran a red light and almost hit him and Jon Voight. Hoffman stayed in character and the line stayed in the movie.

Taxi Driver (1976)

"Are you talkin' to me?"

Robert De Niro did a brilliant job of improvising the entire scene, inspired by a single sentence in the script—Travis looks in the mirror.

Young Frankenstein (1974)

"What hump?"

For his character of Igor, Marty Feldman kept shifting the hump on his back as a joke for the other cast members. After someone noticed, the improvisation was worked into the script.

Goodfellas (1990)

"What do you mean funny? Funny how? … Funny like I'm a clown, I amuse you?"

Joe Pesci based this dialogue on an encounter he had years earlier with an actual mobster at a restaurant where Pesci worked.

Jaws (1975)

"You're gonna need a bigger boat."

Roy Scheider didn't have a line right after his close encounter with a Great White, so he made up this one.

Apocalypse Now (1979)

"You're an errand boy, sent by a grocery clerk."

On location, Marlon Brando folded up pages of the script and turned them into a paper hat, which he put on his head. He later ad-libbed some 18 minutes of dialogue for his character, Colonel Kurtz.

The Third Man (1949)

"In Italy for 30 years under the Borgias, they had warfare, terror, murder, bloodshed. They produced Michelangelo, Leonardo da Vinci and the Renaissance. In Switzerland they had brotherly love, 500 years of democracy and peace. And what did that produce? The cuckoo clock."

Only Orson Welles would have the confidence to add his own lines to a screenplay by Graham Greene.

Silence of the Lambs (1991)

"Hsssssss."

Anthony Hopkins made an unexpected hissing sound right after delivering this memorable line about eating the census taker's liver with fava beans and a nice chianti. He intended it as a joke. The director kept it in the movie, along with Jodie Foster's stunned reaction.

Deliverance (1972)

"Squeal like a pig!"

The most disturbing line in the movie was improvised on set in an effort to clean up the dialogue, with the hope that Deliverance could eventually be shown on television.

Dr. Strangelove (1964)

"Mein Fuhrer, I can walk!"

Peter Sellers, who played three characters in Stanley Kubrick's Cold War satire, ad-libbed much of his dialogue. The lines were later added to the screenplay after they had been spoken.

The Shining (1980)

"Heeeeere's Johnny!"

Director Stanley Kubrick, who lived in England, didn't know the reference to Johnny Carson's Tonight Show. Jack Nicholson's dark joke nearly ended up on the cutting room floor.

There are, of course, many more occasions where this has happened, producing memorable movie lines. This is merely a sampling.
