We continue to refute the rumor that will not die. The latest issue of the otherwise excellent Alter Ego reports that, according to Al Feldstein at a recent San Diego convention, the actor Martin Landau assisted Wally Wood on some of his comic book work for EC. This is not true. I have it from Martin Landau's own, Oscar-winning lips that he never worked in comic books. This is presumably another confusion with a comic book artist named Ken Landau who is no relation and certainly not the same person.
