Apart from Mel Brooks and screenwriter Andrew Berman, the writers of Blazing Saddles included a lawyer named Norman Steinberg and a dentist named Alan Ugo. Both men had always wanted to try their luck at screenwriting, but they both had to go back to their regular jobs toward the end of the process in order to pay their bills.

When Mel Brooks first showed the movie to Warner Brothers' executives, not a single one of them laughed throughout the movie and everything looked like a bust. But when Mel Brooks showed the movie to the company's regular employees, they laughed insanely hard for the whole movie, and the execs decided that maybe regular people were better judges of what was funny. The rest is comedy history.
