I just watched my old TCM recording of "Penelope" (still MIA on DVD and Blu-Ray), and if there are any Columbo fans who haven't seen it, they need to. Falk's scenes are more than just a precursor to Columbo it's practically like watching him in scenes from a lost Columbo episode. Everything is there except the raincoat and the name. His conversation with Natalie Wood practically suggests what an episode would be like if she were a guest killer.
