The answer was Logan's Run!
Congratulations Spacewomanspiff and Maura. Your prizes are 15 brownie points each, your names mentioned on this here blog, a good sized boost to your coolness factor, and the knowledge that you two are some of the proud few that have witnessed the film's awesomeness.
An Honorable Mention goes to Amy who knew the actor in the caftan was none other than Mr. Michael York. Amy gets 8 brownie points.
If you haven't seen it you should really try to pick up or rent it. Here are some yummy 1976 visuals to entice you.
Hope you enjoy the movie as much as I do!
This whole thing has given me an idea. Fiancé and I watch a lot of obscure old movies. I would call us old movie buffs. Would anyone be interested in a "name that film" contest? I'd post a photo from an old movie and people could leave guesses in the comments of the post. I could run them about once a month or so and the fabulous prize would of course be a vintage pattern from my collection. Yay or nay?
