S1·E17 The Adventure of the Sinister Scenario

Ellery and the Inspector travel to Hollywood in order to watch the filming of an adaptation of one of Ellery's novels into a movie. At the studio, they meet the actors who will be portraying them. Gilbert Mallory, the egotistical no-talent assclown slated to play Ellery, is found murdered and once again there's little rest for our weary heroes.
