Arness was making "The Thing", at RKO which was owned by reclusive Howard Hughes. One day the special effects/make up guy took Arness for a walk across the lot to have his final costume approved by producer Howard Hawks. Jim was in his full 7 foot costume with a bald head and wearing the claws. Robert Mitchum strolled by Jim, stopped, bowed from the waist and said "How do you do, Mr. Hughes".
We deal in lead, friend.
