This episode is incredible. As is the other episode with Robert Redford. It's amazing to see these stars on a TV show like the Twilight Zone. Steve McQueen, Robert Redford and Clint Eastwood, legendary actors... legends period. People who act today and do one movie think they are too good for any TV show... Glad to see a change in this with people like Tim Roth (Lie to Me after doing Reservoir Dogs and other amazing movies).

This episode of Alfred Hitchcock Presents is the only time in Hollywood History that Steve McQueen and Clint Eastwood are in the same production. Eastwood in a non speaking extra part , too bad they didn't have a scene together. McQueen would become a star on TV's Wanted Dead or Alive and Eastwood on Rawhide at the same time in 1959. Both of them on the way to major Superstardom and Film Icons.

There aren't many programs that get you in quick, keep you all the way, then give you a jolt of shock at the end the way these shows do. Luv these... interesting, to the point and always with some message.

Reminiscent of several other sci-fi stories, but better--more personal, and more subtle. Raises questions in the mind of the viewer all along the way. Steve McQueen and Arthur Hill were great to watch--completely involved in their characters. I would have no problem watching all their expressions and gestures and listening to their conversation for much longer. This episode could easily have been, or could still be, developed into a two-hour feature film, and I think it really should be. It's a great piece of careful, detailed writing, and all the characters were believable (the wife a little less so, a little less fleshed-out). Shocking twist at the end. I wish McQueen had quit smoking when he had a chance. Such a loss.One question remains unanswered: If Martians don't lie, then what about the ones other than Yang...?I'll definitely watch this again sometime.

Another good Fredric K. Brown story--love those 60's short stories! Something caught my eye when I viewed this tonight. In the opening moments, when Steve McQueen's character turns to go into his editor's office, he places some copy on the person's desk behind him. As he walks to his bosses door, we see the person seated at that desk talking to another standing employee. Unless my eyes are deceiving me, that seated actor is non-other than a young Clint Eastwood himself! Eastwood began his rise to stardom later that same year (1959) as "Rowdy Yates" on the first season of the famous TV western "RAWHIDE".

Thought this was pretty good, other than being horribly predictable. I liked the whole idea of the man left behind and the two civilizations paralleled. Overall, a nice little story!
