Stumbled on a couple old movies...

Any of you ever seen "Twilight's Last Gleaming" from 1977, with Burt Lancaster, or "X-15" from 1961, with Charles Bronson? I came across them yesterday, and I don't know how I'd never heard of them. The first one is about a former Air Force general busting out of prison and taking control of a Titan missile silo in Montana, and threatening to launch the missiles unless the President comes clean about the real reason why we fought Vietnam. The second is about the X-15 experimental aircraft program. If you come across either of these, I highly recommend them!
