Fred MacMurray and Barbara Stanwyck in Double Indemnity The Robert Blake trial is tawdry but it is more fascinating when you take a look at the transcripts of a conversation he had with Bonnie Blakely, after she told him she wanted to keep the baby. Blake flips out, and says things like "You lied to me, you double-crossed me, you double dealt me, and that's who you are...I'm not going to lie about who you are and what you are. 'Cause that's who you are, that's what you are, and that's what you do. And those are big lies, baby, and you can live with that, you know, if that doesn't come down on you." Which is reminiscent of bad B-movie dialogue or classic film noir speak. From Billy Wilder's adaptation of Double Indemnity, based on the novella by James M. Cain:
Walter: Don't let's start losing our heads, that's all.
Phyllis: It's not our heads. It's our nerve we're losing.
Walter: We're gonna do it right. That's all I said.
Phyllis: It's the waiting that's getting me.
Walter: It's getting me just as bad, baby. We've got to wait.
Phyllis: Maybe we have, Walter, only it's so tough without you. It's like a wall between us.
Walter: I better go, baby. I'm thinkin' of you every minute.
