Somewhere along the line, I spotted the odd fact that is the topic of this column and that I'm offering, free of charge, to anyone stuck for a doctoral dissertation subject. It is that an actor who played one famous detective from popular literature back in Hollywood's golden age often played a second.
In the middle of Powell's run as Philo Vance, a rival studio brought out Van Dine's The Bishop Murder Case, starring Basil Rathbone as Vance. Rathbone, as well turned out sartorially as Powell, was much stiffer in the part. He would only find career-changing success as a film detective nine years later, in 1939, when he was given the role he'd been born to play, Sherlock Holmes, in The Hound of the Baskervilles. More on that epic performance at some later time.
What does all this double dipping mean? What does it say about the film business or the actors named or the popular fictional detectives of the day? It's your doctoral dissertation; you work it out. And don't forget to send me a copy.
