Tonight my wife and I are watching the 1993 Much Ado About Nothing. Staged in Renaissance Italy, this delightful Shakespearean comedy has many of the men comfortably shirtless. Just as they should be!
Other good recommendations are encouraged.
Cool Hand Luke and Long Hot Summer.
"Picnic" with William Holden
Bridge on the River Kwi.
I agree with Paul about "White Squall." I can't think of another movie with a comparable amount of shirtlessness. I would add "54" which also has Ryan Phillipe, "Troy", "The Talented Mr. Ripley."
"Miami Blues" with Alec Baldwin 1988.
Just thought of another one "Lifeboat" John Hodiak, oldie, I think he's shirtless for almost the entire movie.
