Jules was almost played by another actor
The original actor who was considered be a shoe-in for the role was Paul Calderon, who’s been in pretty much everything. When Sam Jackson heard about the role, he flew to L.A for a last minute audition. He got hungry along the way and grabbed some fast food.
While walking in, someone said “I love your work, Mr. Fishburne,” and that set Jackson off. He barged into that audition with a burger in one hand, a drink in the other and a wild look in his eyes. That sold Tarantino.
