By the way, Helen Hayes was married to Charles MacArthur who began as a newspaper reporter in Chicago and later partnered with Ben Hecht to write the famous plays, The Front Page and Twentieth Century, and got an Oscar nomination for their co-writing Wuthering Heights.
And her son was James MacArthur, who had a solid career as an actor, best known for his role as 'Danno' on original version of the long-running series, Hawaii Five-0. There was a funny story at the time -- I don't remember the exact details at this point -- where someone on the show wanted their mother to have a small, cameo role on the series, and the show's producer quipped that that would be fine...as long as James MacArthur would get his mother to be on the show, too. In fact, she later did appear, playing Danno's aunt. Here's a clip of the two of them meeting --
Oh, and what the heck, here's a bonus because it's a better clip of her, along with series star Jack Lord as 'Steve McGarrett.'
