Played Don Kirk S5 E33 Tennis, Anyone. Died at 44 in '76. Looks like he last acted in the late 60s. A mystery man. Not anything about his life or death. Just his filmography.

He had a better go at Hollywood than I did.

Last anyone knew he quit his tennis pro job and eloped with Carole.

So many of these seldom seen and unknown actors died at a relatively young age. Drugs booze, sucide? We'll never know!

What's unusual about him not having a bio anywhere is he was in 22 movies & tv shows from the mid '50s- late '60s. A lot of bit actors have a tiny filmography who fell away from acting or novices don't have bios anywhere. But he was a regular working actor over many years.

I wonder if the big shots in Hollywood have any say about Actor Bio's available ?

Looking at his filmography, he was in Target Earth, a fun little scifi film, haven't seen it in awhile, so don't remember him. The film also has Arthur Space who was in the LITB episode Wally's Present.
