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.
In 'Capote vs The Swans: Fact vs Fiction', one aspect to consider is how Capote's real - life experiences might have influenced the fictional elements. Capote was known for blurring the lines between fact and fiction in his works. The 'Swans' he wrote about could be based on real people in his social circle, but with fictionalized details added for dramatic effect. For example, he might have exaggerated certain personalities or events to make the story more engaging.
Perhaps Steve Hibbard was someone who had a tangential relationship to 'Pulp Fiction'. For example, he could have been an acquaintance of one of the actors or directors and had some influence, no matter how small, on the overall feel or direction of the movie. Or he might be someone who worked on the location where the movie was filmed, providing some sort of local support or assistance that was important during the filming process.
