Yes, there was a feature film based on the career of stunt cyclist Evel Knievel in 1974, but that same year also saw an unsold pilot for a television dramatization that purported to reboot Knievel as a crusader for justice.
Sam Elliott, currently the voice-over pitchman for Ram Trucks and Coors beer, was cast as Knievel. The supporting cast includes Noble Willingham, better known for his later work in "Good Morning, Vietnam" and Walker, Texas Ranger, and Michael Anderson, Jr. (ex-The Monroes). One of the first original efforts from Viacom as a producer, not a distributor.
Around the same time, Knievel also had a licensing deal with Ideal Toys.
A couple of years later, a masked stuntman known as the Human Fly followed in Knievel's marketing footsteps, and landed a deal for a comic book from Marvel, which had sold ad space to Ideal for their line of Knievel toys. I don't think Knievel and the Fly ever met, though.
