Female, bi, 29
I second (or third or whatever!) Christian Bale (since the movie “Velvet goldmine”)
Idem for Legolas (but not really hot without these long blond hair)
First of all my crushes : Nick Cave But if he could shave this moustache he has right now !
and his french double Jean Louis Aubert
oops I was forgetting : Nuno Bettencourt rawwwrrrrrrr
well some girls but there are less…
Edith Fambuena , ex-singer of a french group… very hard to find pictures of her now…
Straight male, 37.
Gina Gershon. That body. That mouth. That eyebrow. Lordy.
Is it hot in here?
I think I can add Alan Rickman , in this particular character
Male, 37
Jennifer Connelly, first and foremost; Tea Leoni, and, just this past couple of weeks, have fallen in serious crush with Sarah Shahi.
I might even give up Jennifer for her.
(Am at work, so can’t do the links right now)
Clive Owen, Richard Armitage, Sendhil Ramamurthy and John Abraham.
Viggo Mortensen - actor, poet, artist, devoted dad, ex-punk rocker, activist… let’s just say that it’s a good thing that I think my hub resembles him. 
Ludacris - I’m happy for him that he’s doing his acting thing, but the man raps my panties off.
40, female, more or less straight.
P.S. - Angelina Jolie and Monica Belucci, more or less straight girl’s female options.
42, female.
and the king:
I like 'em tall, dark, and gorgeous!
At work, so can’t risk finding pics, and linking them.
Hetero male, 33.
Sandra Bullock–didn’t think much of her until Phenomenon , and she looked just like an ex-girlfriend. I’m over the ex, but can’t get over Sandy. I gorged myself for two weeks on as many of her movies I could get find. Now I’m just waiting for her to finish her starter marriage.
Anne Hathaway–this young woman is just beautiful. Haven’t seen everything she’s been in, but I’m completely smitten.
Scott Glenn just to see him smile.
Did you mean **Premonition **or were you talking about Kyra Sedgewick in Phenomenon? (Or is there a Premonition not listed in Sandra Bullock’s IMDB listing?)
Male 29
Jennifer Aniston, Helen Hunt, Natalie Imbruglia, the actress that plays Elizabeth in General Hospital …what? My wife watches it.
Better late than never - my perennial celebrity crush, the incomparable, unbelievably beautiful man, Keanu Reeves.
ETA: Forgot another one - Antonio Banderas, but only in movies, not in pictures. I rarely find him attractive in pictures, but I find him irresistible in movies. I’m not sure why that is.
Male, 28, gay
Also at work so can’t find decent pictures, will have to rely on Wikipedia.
Ryan Phillipe
Rupert Penry-Jones best known from Spooks - Rupert Penry-Jones - Wikipedia
Agree with James McAvoy, although I prefer him without the Scottish accent personally.
Jamie Bamber - Lee Adama from Battlestar Galactica - Jamie Bamber - Wikipedia
Michael Trucco - Sam Anders from BSG
And finally a very idosynchratic one of mine, Danny Wallace, the writer of “Join me” and “Yes man” - Danny Wallace (humorist) - Wikipedia
Actually you can see Danny Wallace better in one of his vids - http://www.youtube.com/watch?v=X-CFz9kYBJI (the best national anthem in the world - evah!)
I forgot David Boreanaz - I loved him in “Angel” and I’m loving him in “Bones.” Somehow he is looking younger in “Bones” than he did in “Angel” (and not in a “Mickey Rourke I’ve cut most of my face off” kind of way). Hot, hot man.
Hetero male 56
I’d say my celebrity crush is Carly Simon.
Photo 1 2 3 4
As you may notice from the photos, she started my appreciation for barefoot women. 
And I agree with those who mentioned Gina Gershon and Sandra Bullock for celebrity crushes.
Three pages and no one has mentioned Jessica Biel? I think you guys should stop calling yourself The STRAIGHT Dope.
hetero female, 55
Patrick McGoohan, from days of Secret Agent (Danger Man in the UK, I believe) and The Prisoner, 'cause nothing is hotter than his combination of intelligence and action. And that ironic twist of his mouth.
Viggo Mortensen, for all the reasons cited by Lisa Curl, and more (except for the resembling husband thing)
Alan Rickman, especially in Truly, Madly, Deeply
Gabriel Byrne, sometimes
Sean Connery still emanates pure knee-weakening testosterone
Anthony Bourdain, ditto
John Cusak, Johnny Depp, especially in pirate costume, Matthew McConnaghy, and sometimes even Robert Downey Jr.
David Bowie
!!!
How could I have forgotten His Snarkiness! A thousand times yes.
