What do you think is the best word ever spoken in a movie?
My vote is for Alec Guinness as Obi-Wan Kenobi in Star Wars when we says the word “evil” talking to Luke about Darth Vader and how he turned to evil.
Hmm…
“No” - - Keanu in Matrix with the stopping bullets
“Seek” - James Earl Jones in Conan with the snake arrow thing
- my vote for best one word line
“Daaaaaaaaamn” - Friday - Chris Tucker and Ice Cube after they see the guy with the black eye…
“Impressive.” - Darth Vader to Luke when he jumps out of the cryo tank freezer thing
just a few off the top of my head…

“Woah” --Keanu Reeves, any movie
In Jaws, Sherrif Brody is making a mayday call to the coast guard; Quint comes storming in, wielding a baseball bat, which he uses to smash the radio to bits. After Brody yells at Quint, calling him ‘certifiable’, Quint replies with:
“YahYahYah!”
Okay, somebody has to do it…
Ni !!!
“Khhaaaaaaaaaannnnn!!!” (ST2: Wrath of Khan)
“Fuck” by Sigourney Weaver in ‘Galaxy Quest’.
They dubbed over it, but you could read her lips, and it was very appropriate to the occasion.
“Plastics.”
“Belgium”
Rosebud
I’ll go with “Ni!!”
“groovy”
Dammit, I was gonna say “Groovy!”
“redrum”
Kind of surprised no one came up with either of these two:
“nuance”
“gesture”
Both from the same movie; bonus points if you know which one. 
“groovy”
“No!” - Marcel Marceau, Silent Movie
I second the vote for “plastics”
Mole
Damn! Sam Stone beat me to it. I love that Mel Brooks gave the only spoken word in Silent Movie to mime Marcel Marceau.
Not the greatest spoken word in film, but one of the most notable.
