Too many favorites to pick just one, or even a hundred, so I tried to narrow it down to just one genre, Westerns.
Still too many I love to list them all. The Searchers, obviously, and Shane. The Wild Bunch, The Long Riders, The Magnificent Seven, and the original True Grit.
Many more, but I recently rewatched Will Penny and I had forgotten what a fine movie it is. Went poking around Youtube to post a clip and found this neat little feature where Charlton Heston gives a tour of Paramount Studio's gun room.
