That is Glenn Ford and Erin Gray. Glenn Ford played in a lot of westerns and movies like that, a low key fellow who didn't trade much on machismo like, say, Robert Mitchum or Lee Marvin. Slapping women around really came into vogue in the late 60's early 70's in movies like Peckinpah's or John Boorman's 'Point Blank' in which Lee Marvin smacked Angie Dickinson around pretty good if I remember right. All I'm saying is that it's kind of funny to see Glenn Ford doing this and I don't recognize what movie TV show this is from. His agent must've got him this gig to toughen his image up or something. Oh, and Erin Gray was in one of those science fiction TV shows in the 80's. I don't remember which one. All I remeber is the way her cheesy space age suit hugged her hips and titties.
P.S. I love watching women get slapped around. Like how Mickey Rourke does on Kim Basinger in '8 1/2 Weeks'. He smacks the sh!t out of her for snooping through his drawers while he was at work and lifts her onto a table and bangs the fuck out of her. I masturbated to that scene a lot when I was a child. There was also and Ingmar Bergman movie that had basically the same scene but done more claustrophobic with the camera close in. 'Frustration' or something. B & W. The difference in the Bergman film was that the slaps are louder, the woman screams as she's getting struck, and the camera pans down to show her removing her panties herself to allow in the angry Swedish penish.
