Old-Time Radio Theme Month, Day 28: "Mars is Heaven"
I think Ray Bradbury's "Mars is Heaven" is one of his best short stories, it's a terrific thriller. However, this is a rare case where the adaptation outdoes the original, in my opinion; when the tale was adapted to Dimension X on January 7, 1951. This version includes an extra character, a doctor who was in Dachau as a child and has tried to bury his past. When the rest of the explorers on Mars discover their deceased loved ones now live on the red planet, the doctor is the one man who has no one to meet him.
