Two men who created iconic science fiction characters, in addition to their many other fine performances.
Ricardo Montalban, 1920-2009
Wrath of Khan is not just the best Star Trek film, it's one of the great science fiction films of all time.
Patrick McGoohan, 1928-2009
I am, sadly, only now discovering The Prisoner, thanks to AMC featuring every episode on their website. It's a fascinating show, and truly ahead of its time.
