Brooks had repeated conflicts with studio executives over the cast and content. They objected to both the highly provocative script and the "irregular" activities of the writers (particularly Richard Pryor, who reportedly led all-night writing jams fueled by loud music and drugs). Brooks wanted Pryor to play the sheriff, but Warner executives expressed concern over Pryor's heavy drug use and alleged mental instability.[7] Cleavon Little was cast in the role, and Pryor continued as co-screenwriter. In the midst of shooting, Gene Wilder who had previously turned down the Hedley Lamarr role was brought in to replace Gig Young, who collapsed during his first scene from what was later determined to be alcohol withdrawal syndrome.[8][9]
After an in-studio screening, Warner Bros. executives objected to constant use of the word "nigger", the flatulent campfire scene, and Mongo appearing to punch a horse, and asked Brooks to modify those scenes. Brooks declined, as his contract gave him control of the final cut. He did remove the final line of Bart's response to Lili's attempt to seduce him in the dark: "I hate to disappoint you, ma'am, but you're sucking my arm."[10] To an interviewer's query about his frequent use of "nigger" in the script, Brooks responded that if Blazing Saddles were to be remade today, the controversial word would have to be omitted ("and then, you've got no movie..."). He added that he had received consistent support for its use from writer Richard Pryor, and lead actor Cleavon Little.[11]
