Born 1934 (presumably in California?), Charles Robert Kaltenthaler, Jr. (aka David Love) is a bit of a cipher. I'm not even sure if he's still alive. According to some sources he was last heard from in 2007, but honestly he seems to have disappeared after his appearance in Teenagers From Outer Space.

His involvement in TFOS followed on from his involvement with director Tom Graeff. By all accounts the two were romantic partners, but split shortly after the making of the film. Graeff would go on to have a rather eventful life (check out that last link for details), but Charles seems to have faded into obscurity.

Which is a shame, because his portrayal of the sensitive alien "Derek" was pretty decent. He really did seem like a man from outer space! Then again, one hopes he found a happy, more peaceful life away from the world of low-budget/no-budget film-making.

So, happy birthday Charles, wherever you may be!
