William Goldman may be best known to Western fans as the writer of Butch Cassidy and the Sundance Kid. Ten years later, in 1979, he wrote a script for a movie about Tom Horn. But Steve McQueen, slated to play Horn (right), had a falling out with Goldman and tossed the script.
So Goldman’s work was changed over to the two-part TV oater Mr. Horn, starring David Carradine (left). It was released several months before Tom Horn (yes, there was competition to get out first). Several changes were made to the script, which did not please Goldman.
