I've been picking up a lot of Westerns on DVD lately, and for the most part they've been really good.
Bite the Bullet (1975) - I got this one for $5.50 at Wal Mart. It looked halfway interesting and features Gene Hackman and James Coburn (not to mention Ben Johnson), so I picked it up. Turns out this is a really good "modern" Western, with a different type of story (a 700 mile horseback race). Very well filmed with a solid script and some excellent performances. I'm glad I bought it.
Law and Order (1953)- Ronald Reagan, Dorothy Malone (I loved her brief part in The Big Sleep), Preston Foster, and Russell "The Professor" Johnson. Good cast, good script, some nice scenery and good action. Not a great Western, but a good one, and well worth the $10 I paid for it. Reagan gives an almost John Wayne-esque performance in this one. A fun, entertaining movie.
The Indian Fighter (1956) - Kirk Douglas, Walter Matthau (!), Lon Chaney Jr (!!), Alan "Skipper" Hale (Jr) - another good cast, and a very strong script with some serious sympathies shown to the Indians' side. Some more beautiful scenery, and some great action sequences. A very good Western.
Five Card Stud (1968) - Dean Martin, Robert Mitchum, Roddy McDowall - Slightly different twist on the Western: A Western "Whodunit." Dean Martin is strong as a professional gambler, and Mitchum is very good as a gun toting preacher. An above average script and good acting make this well directed movie quite entertaining. From the same team that brought you True Grit.
I also got Bend of the River, but I haven't watched it yet. I've still got Chisum and Rooster Cogburn on deck as well. Good stuff...
