I remember when Pulp Fiction came out everyone was singing its praises while a few of us recognized that Tarantino had just read every Leonard novel and copied the style (did a great job too).
If you can find Hombre watch it twice, once for the story and then for the dialogue. There are more great lines in this film than in any other (close second is 'Out of the Past'). I've seen it twenty times and I am still blown away by the flood of gems. I watch it at least once a year and after ten viewings my wife finally got why.
Is Crowe going to play the Glenn Ford character or the Van Heflin character? And is Elmore Leonard still alive and writing?
