Adolphe Menjou trivia

OK. Adolphe Menjou IS trivia. To some. But for those of us who spend too much time watching so-so movies from the 30s and 40s, he's an actor you see a lot. Usually he appears as an elegant aristocrat. For instance, this morning I watched Morocco and saw him again. As an elegant aristocrat. I assumed he was French mais non: he was born in the US to a French father and Irish mother. And his cousin was? James Joyce. Yes, THAT James Joyce.
