Here’s a list of Westerns, most from the 50s, available on Netflix Instant Watch. It’s an impressive batch of stuff. (Thanks for the tip, Stephen.)
A particularly interesting one is The Black Whip (1956), a Regalscope picture directed by Charles Marquis Warren. It stars Hugh Marlowe, Coleen Gray, Adele Mara, Angie Dickinson (above), Sheb Wooley and Strother Martin. Wow.
But before you get your hopes up, I’ve been warned that Instant Watch is a real crap shoot as far as transfer quality and aspect ratios go. (Maybe it’s Watch as in “watch out!”) If you give ’em a shot, and they look like they’re supposed to, please let us all know through the comments.
