Ooh, good thread - I've been on a Glenn Ford kick of late!
My very favourite has to be HUMAN DESIRE. He + Gloria Graham = sparks flying through my TV screen.
Followed closely by 3:10 TO YUMA (I can't say I'm looking forward to this year's Russell Crowe remake), The Big Heat, TEXAS (with William Holden), CONVICTED, AFFAIR IN TRINIDAD and THE TEAHOUSE OF AUGUST MOON.
I also like the minor noir FRAMED - inspite of the wholly improbably slick and very wooden Janis Carter, it's good fun for the scene where a truck with failed brakes careens down a mountain, through town, and causes only minor damage to a bumper bar.
