Meh.
I’ll see your Carlyle and raise you an Eccleston.
woof…
Oh good g-d, it’s considered weird to think Jane Weidlin’s hot? Even now, she is smokin’ hot.
Morgan Freeman and I’ve got to second Robert Carlyle.
Kidding? I know some 60 YO that are smoking hot. It’s all in how you carry yourself.
I seem to be seeing more agreement lately, but I always thought Melissa McCarthy was the hot one on Gilmore Girls. Something about her mischevious smile.
Alan Rickman is 65.
Patrick Stewart is 71, as DianaG says!
Pierce brosnan is 58.
Liam Neeson is 59.
Harrison ford is 69.
Come on, people! Old guys are hot!
Seconded.
[brag]I got to say “Hi” to her when Garfunkel and Oates were playing at the UCB Theater a few months back.[/brag] 
Whew! 
Clint Eastwood - 81
William “Big Bill” Smith - 79
Ed Harris - 62
Jeff Bridges - 63
Mikhail Baryshnikov - 64
Richard Gere - 63
Jim Palmer - 64
Eric Clapton - 64
Armand Assante - 60
James Brolin - 69
Scott Glenn - 68
Fred Williamson - 74
And with the exception of possibly Gere and Palmer, I wouldn’t classify these as “pretty boys” by a long shot. There’s just something about them.
For the record, I’m 50.

So old is the new young?
Yaa!
Rob Schneider…hangs head in shame And…I think he’s funny… 
So there’s hope for a mere 48-year-old?
(Just wait till I get those professional photographs uploaded into Arnold’s picture gallery. Just wait…)
That’s because when I get dickish I get suspended. Sometimes at my own request–I think I invented the “Tuba, can you suspend me for a while?” request.
Grant is hot. End of story.
My non-Mythbusters answer: James May, from Top Gear. He’s awkward-looking and only slightly younger than my dad, but when he starts talking nerdy…yowza.
Richard Hammond, from the same show, ain’t too shabby either, but he makes more sense as eye candy, so he doesn’t count.
Hello!
Donald Sutherland is 77. Just sayin’.
Oh oh! I think I might win. I’ve been gaga over David Letterman since I was like 17. (He’s 65-ish now?) Obviously, I do not discriminate based on age. I mean aside from being smart and clever, I do honestly think he’s physically attractive.
There’s a hilarious bit when David Tennant comes onto Top Gear, and they’re like “You’re a good-looking version of the Hamster!”
yum… harrison ford AND pierce brosnan. i’ll be in my bunk…
