Mike McCoy -- stunt man and producer -- has commissioned writer David Baxter to create the screenplay already titled Challenger. The Bandito Brothers already have a documentary in the works as we speak called Gearhead: The Legend of Mickey Thompson -- I think they have a heart felt interest in the man and their interest is contagious. I've only been aware of him for about an hour now and cannot stop searching for more information on him.
After reading (let's say, everything Google brings up) about Mickey Thompson I believe both the upcoming documentary and the film will sit well with audiences if done well. Thompson's life was an interesting adventure with a brutal end -- perfect for any Hollywood script. It's just unfortunate the entire thing isn't one fantastic piece of fiction.
