Yes, I met Striepeke on HARRY AND THE HENDERSONS and later saw him again on CATCH ME IF YOU CAN and he doesn't look like that guy, even if it was so many years before. That guy looks more like Sydney Pollack or his brother Bernie the costume designer. The photo also names John Chambers who is not in the shot at all.
Here's a cool photo of Hunter and Heston checking out the corpse of the female astronaut Stewart who didn't make it through hypersleep. Looks like they are in the prop shop. Behind the scenes from the first film.
I'll bet the Ed Sullivan appearence had something to do with promoting DR. DOLITTLE. I'd love to see it -- if they were on a broadcast -- as I've never heard Arthur Jacobs voice, just seen images of him. He's in a newsreel promoting WHAT A WAY TO GO! on that film's Fox DVD, but it's silent.
