My uncle was the head of the projection department at Paramount Pictures for a long time, and he knew I liked Star Trek growing up. When we went to visit once, he gave me a VHS tape of Forbidden Planet, only saying I'd like the part that showed them decelerating, which used the same film technique as the transporter on the original Star Trek. Of course, I think I wore out that VHS tape by watching it, and especially enjoyed Leslie Nielsen's performance, who at the time was starring in the Naked Gun pictures. Anyway, Forbidden Planet is an absolute gem and holds a special place in my heart.
I understand Robby had a presence in other features too.
