Just got my copy of Movieline Magazine and there's an amusing article called "You Can Leave Your Shirt On". It mentioned how lately middle aged actors decided to show-off their abs and pecs. Harrison Ford in What Lies Beneath, Robert Redford in The Last Castle, Kurt Russell in 3000 Miles to Graceland, Pierce Brosnan in The Tailor of Panama and many others. Not only is the pretty much in-shape, over-40 crowd doing it, but the over-50, over-60 sets are taking off their Ts as well. Do we really need to see the stars of Space Cowboys like Donald Sutherland and James Garner naked? Or Anthony Hopkins repeatedly takes off his shirt in Surviving Picasso. It's a disturbing sight and cruel to the actors, the article argues.
By the way, the same issue list "The Screen's 20 Most Seductive Scenes".
