I believe didn't it have something to do with blindness?
I read in "The Twilight Zone Companion" that in TZ: The Movie, originally the re-make of "It's a Good Life" (Joe Dante's segment) was supposed to be the last one, and that the house was supposed to blow up. Katherine (?) gets away, and hitchikes with Dan Akroyd of course....

A lot of people consider the "happy" ending to the Dante segment kind of lame. (especially since the original ended much differently.)
Plus the whole thing with Vic Morrow (the racist in the opening segment) and the two little kids getting killed was a big scandal, which is understandable of course. Originally he was supposed to save the two Vietnamese kids, and that was the ending. But because of a special effect going wrong, Morrow and the two kids (both illegally hired) were killed.
I guess they edited it by attaching a deleted scene or something? (Morrow being taken away in the truck) That's my guess.
