Full shows on AOL Video
You can watch full episodes on http://video.aol.com. I just watched the one with Robert Duvall, The Giant Killer.
AOL's Flash video player really blows though. You can't stop the video once you start playing it fullscreen! Even worse, it doesn't work at all in my copy of Firefox (YMMV). I have to use IE to play it. Fortunately it does stop at the commercial breaks so you can take a break. It plays one 30 second commercial for Tylenol or Best Buy and then you can go full screen again. They have lots of other classic episodes there including Man From Uncle and I Spy.
I just wish they'd use a better player.
If your favorite movie was made during your lifetime you haven't seen enough movies.
