OK, I will bring the Donald Sutherland stuff into this thread tomorrow.
The real deal is that the only hot actors to me are those who can do love/sex scenes as though they can believably be in love and sexual at the same time
I am sure there are more (please post!) but the only ones I can recall off the top of my head are Al Pacino (fabulously in Sea of Love, but in lesser movies, too), Dennis Quaid in The Big Easy (have noticed it so much in anything else), and Donald Sutherland (in Klute and Don't Look Now).
I want more examples. I really can't remember any others, though.
