William Shatner had in the classic episode of The Twilight Zone (1959) "Nightmare at 20,000 Feet" played a plane passenger recovering from a nervous breakdown who is unable to convince anyone about the strange creature he keeps seeing on the aircraft's wing, portrayed by Nick Cravat. When the story was redone in Twilight Zone: The Movie (1983), John Lithgow played the passenger and the creature was played by Shatner's co-star here, Larry Cedar.
