I saw this series first run and Not since but every time I see Powers Boothe this is what I remember. I may or may not have seen Bogart's portrayals at the time, I know I have since, but this is the more memorable Marlowe. Boothe was a relative unknown at the time. He'd played Jim Jones and then came this, hence it was a great time for him to step into a well known role and own it! Advertising at the time made a deal out of it being HBO's "first" something. First drama or first shot on film or something. I've forgotten what but the show was very worthy of the hype. I'm going now to search for a copy of the DVD. I think it's time to revisit this little gem!
