T-Men (1947) review

The U.S. Department of the Treasury gets two agents, Dennis O'Brien (Dennis O'Keefe) and Tony Genaro (Alfred Ryder), to go undercover and hunt down a bunch of bill counterfeiters ... except the organization goes surprisingly deep.  I get that it's American Propaganda (look at how far we'll go to find you) and a composite story (drawing from multiple cases), it really does strain plausibility at every turn: they make it seem like being a "T-Man" is about as dangerous as being a case officer for the CIA in the Middle East.  What it does manage to do right is set the mood: the cinematography by John Alton is stark and unforgiving, and the movie does a good job suggesting that there's a lot of seediness going around in poker rooms and bath houses.
