Hollow Triumph: loved it! Never saw the twist coming, though it was obvious something was going to go awry with the scar on the wrong side of his face! Bartok seemed so uptight, it must've seemed inconceivable to Muller that, in his own way, Bartok would be in trouble every bit as deep as what he was running from! The end scene with people walking past Muller's body was quite shocking too.
Crossfire: Not, I think a particularly Noirish film with the exception of some of the cinematography but a very important film though for it's subject of the insidious nature of race hate. I thought it has a particular resonance today too in light of the recent events down in Charleston. Some superb acting too from Robert Ryan, who really owned that role as the racist killer and Robert Young as the weary detective: Mitchum, though, I thought was a little underused, which was a shame.
I completely agree with all your points on Crossfire. I kept thinking of the Charleston gunman as Robert Young was explaining how hate takes root and explodes into death. It just made me sad. But I also thought it was interesting that he only talked about prejudice based on religion. Not on race.
And yes, we needed far more Mitchum than we got. His role was odd. I kept expecting his character to grow in importance as the investigation progressed, but he never really did.
And I love seeing Gloria Grahame in anything. I've only seen her do bad girl roles, so I don't know if she ever had a chance to branch out, but she does bad girl great.
