I have season 2 on DVD and that has the John Cassavetes episode (which also features Myrna Loy) as well as the Leonard Nimoy one (A Stitch in Crime) and Anne Baxter’s Requiem for a Falling Star and also (one of my favourites) Dagger of the Mind.
Loved all the shows with Patrick McGoohan, who was not well known in the US then but huge in the UK. His real life daughter also appeared.
Far from my favorite episode, but William Shatner as a radio talk show host, which I always figured was a veiled imitation of Rush.
I have all of them I think.
There were a lot of NBC mystery movie shows that didn’t go far that I’d like to see released. Fat chance.
