Richard Haydn played gay AND straight roles...in a Dick van Dyke as old radio comedian, and in "Sitting Pretty" 40s comedy film with Clifton Webb in his first of 3 Mr. Belvedere roles AND Maureen O'Hara, married to Father who Knew Best, plus Ed Begley senior...was the funny butler in "And Then There were None", a friend type in "Please Don't Eat the Daisies" film...a fine talent.
What a bizarre-looking video... has it been modified in some way? It just doesn't look like the film of an original Twilight Zone episode. (These days I suspect AI to be behind all video that looks weird or otherwise "updated" and creepy. ) I thought I had seen them all... Now I need to go and check out the original... minus the enhancements.
You never go wrong with the always awesome Ross Martin as a supporting character! Loved him on Wild Wild West and "Will the Real Martian Please Stand Up?" episode of TZ
The TV repairman is Barney Philips, who played the diner cook with the third eye in his forehead, in the Twilight Zone episode "Will the Real Martian Please Stand Up?"
