I thought he and Lee Grant made a wonderfully horrible married couple in Airport '77. Olivia DeHavilland, Brenda Vaccaro, Joseph Cotton, James Stewart and Jack Lemmon were also in that camp classic. Christopher Lee Grant, I thought, could have made a great recurring couple in dramas. I think they'd even make a great George and Martha in Who's Afraid of Virginia Woolf!
Lee starred as Dracula nine times, including in the films Horror of Dracula, Dracula: Prince of Darkness, Dracula Has Risen from the Grave and Taste the Blood of Dracula.
A WW II veteran, he also starred in two of my all-time favorite Brit horror films: Horror Hotel (City of the Dead in the UK) and Dr. Terror's House of Horrors. He died of respiratory complications (not a stake through the heart).
