Seabrookians may find of interest the fact that two Kansas City, Missouri playwrights have worked the Hex Hitler Party into a new play, Hexing Hitler.
Judging solely from their website, they have taken egregious liberties with historical facts. (For example, there were far more than five people at the real party, and Constance Kuhr, who plays an important role in the play, was not one of them!) Given the many mistakes in the comments of the actors, I doubt they have a very production that is very faithful to life. However, here is a largely favorable review.
If anyone sees the thing for themselves, I'd be interested to hear about it.
