In 1975, Warner Brothers filmed a sitcom spinoff of the hit movie, Blazing Saddles, called: Black Bart.
The sitcom starred Lou Gossett Jr., featured pale imitations of the original cast, and had a canned laugh track. The only reason Warner Bros filmed the sitcom was due to a clause in Mel Brooks' contract - with the intent of producing a Blazing Saddles film franchise. Four seasons were filmed - and it was never meant to see the light of day.
