Martin Landau has died

Here he is as the commander of Moonbase Alpha in Space:1999, in which he starred with his wife Barbara Bain - though I first knew him as a member of the Mission:Impossible team. He was Rollin Hand, the master of disguise. He also appeared in films like North by Northwest, so he had quite a varied career over the years including, apparently, turning down the role of Spock in Star Trek!
His daughter is Juliet Landau, who played Drusilla in Buffy the Vampire Slayer.
