“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.
A Nightmare on Elm Street 3: Dream Warriors
“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.
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."
Mrs. Doubtfire
“Do you want some cream?”
The scene: Mrs. Doubtfire’s face is dripping with cream that falls into a social worker’s coffee. "Mrs. Doubtfire" will forever remain in our memories as one of the funniest, most original movies ever, (thanks in part to Robin Williams). It’s packed with hilarious scenes throughout.
For example, when the cream starts dripping into the social worker’s cup of tea, Mrs. Doubtfire says, “Do you want some cream?” This line was utterly improvised because the set lights caused the actual melting of the cream! This movie is accurate and will always be a household name across the United States.
Edward Scissorhands
“He didn’t wake up.”
The scene: Peg asks Edward where his father is. Tim Burton's classic was "Edward Scissorhands" being anyone but Johnny Depp. For example, in the scene where Peg (Diane Wiest) asks Ed where his father is, he innocently replies, “He didn’t wake up.”
The original script read, “He died,” but Depp thought this made Edward look too guilty because people would assume he murdered his dad by mistake. Also, Depp took out almost 90% of Edward’s dialogue because he thought it made the character appear shyer and more innocent. Or maybe Depp just didn’t want to memorize that many lines.
