“Welcome to prime time, b**ch!”
The scene: Freddy Krueger pops out a TV and kills a kid with it. Freddy Krueger (Robert Englund) became a symbol of evil, and the fact that he’s such a terrific actor made it all that much scarier.
In 1987’s “A Nightmare on Elm Street 3: Dream Warriors,” Freddy improvised one of the best lines in the movie, saying, “Welcome to prime time, b**ch!” while he rips out a TV set and kills one of the characters with it. You have to admit, apart from the whole being a terrifying horror film, that line is quite hilarious.
His Girl Friday
“The last man who said that to me was Archie Leach.”
The scene: The Mayor tells Walter Burns that he’s through. “His Girl Friday” is a classic from all the way back in the 30s.
When murderer Earl Williams (played by John Qualen) is found at the desk, the Mayor says to Walter Burns (played by Cary Grant) that “whistling in the dark isn’t going to help him this time. You’re through.” Walter replies, “Listen, the last man that said that to me was Archie Leach just a wee before he cut his throat.” Grant completely improvised this line, which was particularly funny since Archie Leach was Cary Grant’s birth name!
When Harry Met Sally
“I’ll have what she’s having.”
The scene: Sally screams out as if she were having a climax while eating with Harry at dinner. The “When Harry Met Sally” movie produced many famous lines that are still quoted to this day.
Everybody remembers that infamous scream that Sally, played by Meg Ryan, busts out, making every single dinner turn their head in awe, with an old lady even saying to the waiter, “I’ll have what she’s having.” You’d think that was definitely in the script, but no! It was completely improvised at the suggestion of Billy Crystal, and it worked like a charm.
Broken Arrow
“Yeah. Ain’t it cool?”
The scene: Riley Hale tells Vic Deakins he’s out of his mind for stealing a nuclear warhead. In the 1996 “Broken Arrow” movie, Travolta plays Major Vic Deakins, a renegade soldier who steals a nuclear warhead, and Captain Riley Hale (Christian Slater) has to find a way to stop him.
One of the best scenes in the movie is when Hale tells Deakins, “you’re out of your mind,” and then Travolta, completely improvised, answers, “yeah. Ain’t it cool?” Completely unhinged, absolutely perfect! Woo loved it so much that he used it in the next film he starred in the following year - "Face/Off."
Avengers: Infinity War
“I’ve noticed you’ve copied my beard.”
The scene: Thor and Captain America have a friendly conversation during the Wakanda fight scene. During the epic Wakanda fight scene in "Avengers: Infinity War," there’s a moment when Captain America (Chris Evans) and Thor (Chris Hemsworth) are having some funny light-hearted banter, and Thor suddenly says, “I’ve noticed you’ve copied my beard.”
This line was completely improvised and made audiences laugh, considering their beards were basically the same at the time. Directors Anthony and Joe Russo commended Hemsworth for the ad-lib, saying it added a perfect element to that scene’s short conversation.
