Previously, I noticed that many times they changed the ending and not too cleverly. In chapter 8 when the Marvel took the dive off the roof the action the next week was different and obviously sneaky, not a true cliffhanger! Oh yes, the agent who knifed the thug in bed after he identifies the Marvel was the Marvel technically. Tom Steele played the assassin and of course was killed again in the car crash. He is as you know the man behind the mask in all the action scenes. If you watch closely you can identify his stance, body language and physical running attitude. He was never mentioned in the credits at all. Most curious.
