In the movie, Leonardo DiCaprio's character name is Rick Dalton and is based on actor Burt Reynolds, similarly, Brad Pitt's character name is Cliff Booth and is based on stuntman and filmmaker Hal Needham.
For the other actors and their characters, they use the exact same name as the actor based on.
