The tv execs set him up. I distinctly remember all the MASH actors emphasizing that one point.

They gave him a choice, play the lead or you’ll never act again. It would have been wiser for him to tell them to shove it and then go into theatre until a good part came along.

The only thing show business will not forgive is failure.

I remember the character who played Radar saying about Stevenson "He didn't leave to go do Hello, Larry." IIRC, in that interview he or another person said that Stevenson departed because of lack of basic comforts for the actors (whatever the specifics, I am not sure).
