I hesitated before watching, because though it holds the talents of Kazan, Neal, Matthau, Remick and others, it stars Andy Griffith. The corn pone, folksy persona he almost always displayed throughout his career is unappealing and boring in my opinion, no matter how successful he indeed was. But in this role, with the script and direction he utilizes, he gives a riveting, eventually maniacal performance that I never would have thought he had in him.
I found it particularly engaging and chilling as I watched, drawing parallels between his story and that of the Orange Wannabe Fascist moron I know and loathe. Hits very close to reality in not all, but many, respects. Gullible, seemingly willfully supporters and lackeys blindly following a raging moron with his self-created bully pulpit.
I recommend watching.
