Leo Penn was a very good director. He did a lot of television, and I thought he did a good job on The Enemy Within. The shooting data in Cushman's book is useful because it shows why some good directors like Penn and Harvey Hart were not invited back in spite of doing good work. I think Johnson's original ending (in which Crater survived) for The Man Trap would have added a lot more emotional weight. It would have made the creature less opportunistic and also would have made Crater seem tragic rather than gullible. At the same time, Roddenberry's added line of "A year...or was it two?" is pretty great. I liked the actors and the noir atmosphere in The Four of Us are Dying. Not a top favorite Twilight Zone, but I enjoyed it. Interesting blog, Nelson. Funny that we were just discussing Spock's Brain. There are definitely a few factual errors in the Cushman book, but they aren't pervasive. I also noticed the Riley in The Man Trap claim. I watched for it when I screened The Man Trap this weekend and I didn't see him either. I did notice the two opening bridge shots from The Naked Time, especially since I never knew why they were there before reading Cushman's book.
