Howdy Manco!!
About the only thing I know about Phillip Terry, is that he was in a couple of 1940's films, Wake Island and Bataan, in supporting roles. He was married to Joan Crawford for a time and then he retired for a while and when he returned to Hollywood, he was in a few B Horror flicks like, The Leech Woman and another with Mamie Van Doren.
I best remember James Broderick from his role as the patriarch of the 1970's t.v. series, The Family, with Sadie Thompson and Meredith Baxter and the very young Kristy McNichol. He is also the father of Matthew Broderick, who you will remember from Ferris Bueller's Day Off, War Games and Godzilla.
