Elmore Leonard recently turned 84. 84! This guy has been around for a long time. He started out writing westerns and really made his mark--as far as sales go--in the crime genre. I tend to enjoy his earlier work better than his later work, which is not to say that his later work is bad. But his early stuff, including the westerns, is marvelous.
So here, for your viewing enjoyment, are trailers to four films based on Mr Leonard's early work...
1971. Valdez is Coming
1972. Joe Kidd
1974. Mr. Majestyck
