Tommy Kirk (Guest Star In" moon pilot")
Charlton Heston (Three Violent Men) This page offers a good review on the movie.
David James Elliott (This guy really looks like Tom Tryon. And he's a great actor as the star in the hit series "JAG". If the life story of Tom Tryon is ever made he should play the part (or a re-make of "Moon Pilot"). Just my thoughts)
Randy Vasquez (Ok, he has nothing to do with Tom Tryon. But he's a great actor who plays the gunny in the TVshow "JAG".)
