In the IMDb summary of this movie, they young man who played the boy in the film is not listed. He's the one Ben (Martin Milner) was trying to put in the bed and kill because he knew to much. Anybody know the young man's name?
The boy is "Buck Zorba", The young actor who played him was Charles Herbert -- he's the first name listed in the IMDB cast list. I know YOU are but what am I ... Infinity !
That means they had to convince the boy to star in the movie, meaning he could afford to be picky about roles. It's kind of unusual for his age at time.
From what I have heard (I was only 3 when this came out) Charles Herbert was one of the most popular child actors of his day. Apparently William Castle (the director) really wanted him in the film; so much that he was offered top billing.
The only other child stars I can even think that can come close to that caliber of fame over more experienced adult actors would be the boy who played Beaver Cleaver from Leave it to Beaver and, of course, Shirley Temple.
Oh, and Jackie Gleason too, the one who plays Uncle Fester in The Addams Family.
I was born far after this film's release. It's cool that we can talk about it to each other, appreciating what makes it special in spite of our age difference.
