Speaking of Arness and his role in "The Thing", I once read an interview with Ken Tobey in which he described playing a part in a "Gunsmoke" episode. Arness, according to Tobey, didn't speak to Tobey about their working together in "The Thing" BUT a half hour before Tobey's part in the episode would have finished, Arness declared he was too tired to work any more. The scene had to be completed the next day which meant Tobey got an extra's day pay.
