This is WB doing a Vitaphone Technicolor short on Patrick Henry. The highlight is his bombastic inspirational speech inside the Virginia legislature as he argues for arming the militia and abandoning any more negotiations.
With Europe in turmoil, it's easy to see the subtext in this freedom-loving historical short. It's pumping up the patriotism. It feels like a poor version of Masterpiece Theater until we get to the big speech. There is no doubt that the speech is a big crowd pleaser and I'm sure that the audience of its day loved it. This did win the Oscar for color short. The Technicolor probably helped a lot.
