I finally placed who Paul Blackthorne (Det. Lance) reminds me of. I was watching "Treasure of the Sierra Madre" yesterday, and, in the scene right before Dobbs shoots Curtin, when Dobbs is ranting, I realized that, from the upper lip to the chin, Humphrey Bogart and Blackthorne looked a lot alike. Trying to place what was familiar about Blackthorne was bad enough when he was on "Burn Notice", but, with the beard stubble, his being on "Arrow" was really getting to me. I'm glad that's settled.
