handsome men of certain age, silvery haired. bland? douglas can seem coolly evil, is more interesting - but can be bland, unlike: christopher watkin. sean penn. and you couldn't exchange kevin bacon for any of these without it seeming a different character - he's, what, boyish -

anyway, anyone talking about these two as interchangeable? esp in the deadly-affair genre?
Michael Douglas vs. Richard Gere "That part could have so easily gone to Michael Douglas, and it wouldn't have made any difference to the movie." That got us thinking that the last several roles on both Gere's and Douglas's résumés are pretty interchangeable. You could substitute one in any of the other's movies and not think it much of a stretch. ahhhh, exactly.
We defy you to pull up both actors' CVs on the IMDb, choose any movie at random from the past ten years, and find an instance where the one actor was so perfectly cast, and made the part so indeliby his own, that the other wouldn't probably have done just as competent a job. It can't be done, because they are, at this point, pretty much the same.
