What caught my eye here is the illustration and the clever use of the tagline. I also like David McCallum and Lloyd Bridges. Keenan Wynn's kind of fun to watch, too. And how can you pass up Marshall Thompson (It! The Terror from Beyond Space)?
I briefly met David McCallum in the 1980s, when I was shlubbing the shelves at B. Dalton's Software Etc. store on 5th Avenue in Manhattan. He was close to my height (okay, yes, short!), so we could see eye to eye. I liked that. I forget what computer program he was looking for, though.
