Steve Earle was indeed in Pulp Fiction. His appearance as a drug dealer was quite memorable. In the movie, which is known for its complex and interwoven storylines, his character was part of the criminal elements that populated the world Quentin Tarantino created. His performance contributed to the overall edgy and unpredictable feel of the film.
Yes, Steve Buscemi was indeed in Pulp Fiction. In the movie, his character contributed to the complex web of stories and characters. His performance was part of what made Pulp Fiction such a cult classic, with his unique acting style blending in with the other great performances in the film.
I'm fairly certain that Steve is not a character in 'Pulp Fiction'. The movie is known for its complex and intertwined storylines involving a relatively small number of main characters, and Steve is not one of them.
