Geesh, I did IMDB searches on some of these dudes and none are 20 years older than me. I was born in 1955. Well yeah Cary Grant would be (1904!!!).
Robert Redford was born in 1936 (I actually got his autograph once while he was making the movie, The Way We Were!!!)
Morgan Freeman was born in 1937
Sam Elliott was born in 1944
Tommy Lee Jones 1946
Armand Assante was born in 1949
Ed Harris was born in 1950
Pierce Brosnan was born in 1953
So guess I will stick with Paul Newman (1925) and Sean Connery (1930). I also thought Christopher Plummer (1929) was so handsome in The Sound Of Music.
And, MRD, you can have Burt Reynolds (1936)! Ewwwww!
