>>345613Travolta in Saturday Night Fever was pretty good, memes aside. In Pulp Fiction he didn't really act, they were just rehearsing a cartoonish version of a previous role, for example Travolta was doing a Fever/Grease joke.
Willis was just being Die Hard and Jackson was being an overly dramatic hood nigger like in Menace 2 Society/Juice.
It's all a con, "act like in that movie bro, just relax" is a simplistic retarded instruction but it does really work when the actors are seasoned, either bad or not.
