Yes, this is another one of those shallow and twisted 'go for beauty instead of talent' threads. When I was young these threads wouldn't exist, and people had posters of Mao Zedong in their bedrooms

So, what's the best looking actor and/or actress in your eyes? It doesn't really matter how old they are now, what matters is their peak beauty that impressed you.

My favorite used to be Teri Hatcher, now I'm in love with Amy Smart.

Methinks Keira Knightley looks divine.

I know there's a few actresses that I find beautiful or downright gorgeous, but I can't think of them at the moment.

However, the first one that does come to mind is Zooey Deschanel. She's dreamy!

Girl: Christina Ricci
Guy: Ryan Gosling.. Yeah I said it

Entirely too young for me, but Victoria Justice is extraordinarily pretty.

As for actors, I think Borat (Sacha Baron Cohen) looks great. They made him look like 20 years older in Borat, but in Bruno and The Dictator he looks much better. http://3.bp.blogspot.com/_B1LlYh6iKqs/TAn-7tcpmlI/AAAAAAAABhQ/bSjouLEpQ_M/s1600/sacha-baron-cohen.jpg

Scarlett Johanson, She is a goddess! All natural to!

Raquel Welch

/thread

The blonde chick from Gossip Girl is stunning. I also like the doctor from Lost, Matthew Fox. When I was a kid I was a big Van Damme fan, I wanted to look just like him and I think I do

Yep,
And I'll add Jane Russel, Sophia Loren and Kat Hepburn (she's like Mary Anne from Gilligan's Island for me)

I think Halle Berry has a timeless look as well

I think tons of actors and actresses are good looking. Both male and female, I don't have a problem admitting a guy is good looking in a non-sixual way. It's more out of admiration than attraction, really. If that makes sense. Like, I'd want to be like them, not with them.

Ryan Golsing is definitely on that list. So is a young Brad Pitt (Fight Club, Troy, Snatch era), George Clooney and Christian Bale. Of course, I think tons others are good looking, what I really want to shoot for is to be a classy, charming, sophisticated kind of guy. These guys have all had roles in which they are just that.

Gosling - Crazy, Stupid, Love
Pitt - Oceans 11, 12, 13
Clooney - Oceans 11, 12, 13
Bale - American Psycho

Of course, Bale has a little edge to him in his film, but you guys get the idea.

Now for actresses...

Emma Watson
Christina Ricci
Kate Beckinsale
Jessica Alba
Ashley Greene
Ellen Page
Amy Adams
Jennifer Love Hewitt

I could go on forever...

Audrey Hepburn.

Brigitte Bardot and Alain Delon in the early 60s

Also Claudia Cardinale, Lauren Bacall, Marina Vlady and Jane Birkin, among many others.

I gotta second Cabius on Scarlett Johannson. Of the well known actresses, she's my favorite. My favorite overall, though, is Katie Cassidy. In case you don't know, she was on the remake of Friday the 13th, and also a few tv shows like Supernatural, Harper's Island, and the new show, Arrow. She is just insanely beautiful to me. Her eyes are mesmerizing.

Mila Kunis

I always thought Katherine Hepburn was particularly attractive, with a good acting talent as well.

As for males, Marlon Brando appealed to me as a fellow man.

I'll jump in the shallow water ha and add that I've always thought Salma Hayek is gorgeous, when i first saw her in Desperado and From Dusk til Dawn i thought OMG. I also like Zhang Ziyi for her natural beauty http://www.meiguoxing.com/images/Zhang_Ziyi_-_Crouching_Tiger_Hidden_Dragon.jpg

As for newer actresses, I think Freida Pinto is simply stunning http://3.bp.blogspot.com/_036yF3LHHa0/TG-FhV4826I/AAAAAAAAGsU/efM5aH3fURo/s1600/Freida+Pinto+New+York+Times.jpg

Natalie Dormer

Edit:


I'll see your Raquel Welch and raise you a Caroline Munro.

Claudia Black. Not just for her looks, but her amazing voice. She is the main reason why I want to play Uncharted 2 and 3, she is one of the reasons why I keep going to back to play Dragon Age: Origins.

Emelia Clarke

I vote Evilfish1 for most beautiful actress.

actor: cary grant
actress: louise brooks

Oh heavens, I could make a list using a microscopic font that would still be 10 miles long if I tried to list all the actors I've thought were at least fairly handsome. There is no "best."
My taste tends to go from rather odd to rather "typical". That said:

Ralph Fiennes
Kevin Spacey
Denzel Washington
Simon Baker (The Mentalist guy)
Tom Hiddleston
Ken Watanabe

...and on and on and on and on....

Females? Eh...just like with the guys, I think lots are gorgeous, but since I don't want to put them on my desktop as wallpapers, I'm not going to bother...
