This is a great made for TV film, sporting a deep bench of wonderful actors. This is the kind of made for TV stuff above budget and vision of the major networks now. However, is this movie accurate history? Well, very few honest intellectuals could defend Joe McCarthy unless maybe after several big gulps of Jack Daniels. That said, a few facts? HUAAC was a House organ, not directly tied to the Senate in any way, and McCarthy was a Senator. Point being, there were lots of witch hunters back then. For purpose of drama, both this film and history have settled on McCarthy as the sole and thorough bad guy.
McCarthy directly hurt very few lives. He did amplify a current of nervousness already running through America, and this spawned many imitators. These Monkey-seers Monkey-doers were even more hurtful than Joe, by sheer force of numbers alone.
To honest intellectuals, it seems obvious Joe McCarthy couldn't catch a cold at the North Pole. As "The Haunted Wood" (Allen Weinstein) reveals, from briefly opened Soviet archives, there were plenty faithful Communist spies operating in the US. McCarthy...Keystone Cop versus Houdini basically.
If one can understand there were dangerous Communist spies working hard in the US in the early 1950's, but they weren't in Hollywood, they were in Washington. If one can understand early 50's Red Scare was kind of hangover from VE & VJ day, following Soviet detonation of A-bomb. If one can understand Joe McCarthy was not evil genius of persecuting many good folk who just held harmless unpopular views (personally, I wouldn't trust Joe McCarthy to mow my lawn) but only somebody who blew on something already smoldering? Then by all means watch this movie and enjoy it. It is well made with some wonderful actors. But it ain't accurate history.
