Lee Remick!
This has been one of my favorite films since I first saw it.
Love the plot, the contrast between Steiger's wonderful over-the-top acting and his subtle "theatrical" characterization.
George Segal does a great job as the bumbling cop, sharing with Steiger's character the overwhelming presence of a mother figure.
But I'm surprised no one mentioned the beautiful Lee Remick!
Perfect as the "gentile" counterpart to Segal's Jewish cop, she's as gorgeous as ever and perfectly (WASPily?) understated in her attraction for Segal's character.
Wish this film would be show more often on TCM!
