Butch Cassidy And The Sundance Kid
(20th Cent. Fox, 1969)
Made for a whopping $6M, and turning in over $100M (back when $100M was considered a lot of money in an era of $1 tickets), this movie is not only a great film, a classic western, and the buddy movie archetype that catapulted Robert Redford onto the movie star A list forever, it's an incredible result of all the ways Hollywood could have royally screwed up a movie but didn't, when you look at the parade of talent they considered miscasting for the roles (including originally switching Redford and Paul Newman's parts). The only tragedy of this movie is off-screen: looking at Katharine Ross in her follow-up to The Graduate makes one wish she'd done another 50 movies.
