I bear a very strong likeness to musician Me’shell Ndegeocello (2, 3).
But with hair.
Nicholas Cage.
Personally, more like Yoda I think it is.
Tobey McGuire, kind of.
Prince Edward (not exactly a celebrity)
At the time, Ben Cross and I looked quite similar, when Chariots of Fire came out in 1980… the cadaverous cheeks, the beetling brow, the knobbly nose.
Happily, we’ve parted company since.

I get Eddie Izzard from time to time.
Usually when I’ve got slap on, now I think about it.
One of my best friends insists I look like a “Jewish Bjork”. I don’t see it myself : shrugs :
I strongly resemble a young Robert Redford. I’m 33 yrs old about 6’1" lean 200. And blond hair hazel eyes.
I’m quite regularly told I look like either Richard Branson or Shaggy from Scooby Doo.
I think I look a lot like a scarecrow (shoulder length, unkept blonde hair) with a goatee
In the elevator, two girls are eyeing me suspiciously. I know the look. Finally, one of them says to me, “Do you know you look like–”
“Richard Dreyfuss,” I finish.
“YEAH!!! That’s the guy, right, from ‘Mister Whoozit’s Opal’? You get that all the time, I bet.”
“This is the first time I’ve heard that,” I say, with years of polished timing. “Today.”
I don’t really see it myself. I’m sure if I were told it was a more studly character, I’d endorse it, though. My girlfriend, however, did tell me when we met that she thinks Dreyfuss is very attractive. Which is why she’s my girlfriend, I suppose.
Kenneth Branagh supposedly - when he still had the beard that is. If fact people commented on the likeness before either of us grew a beard, then I grew one and he just had to copy 
bjohn13, you can be my boyfriend if I ever go back to middle school!
Like nuthinboutnuthin, I used to “get the Ann Margaret thing.”
I want to look like Heidi (the redhead on CNN) but there ain’t enough plastic surgeons in the world.
That’s EXACTLY the problem. I used to go into a lot of people’s houses…and I saw a lot of 12-13 year old girls and boys with Harry Potter posters.
Of all the things in this world that I want to be, I do not want to be worshipped by 12-13 year old girls (unless, of course, one happens to be my daughter).
Plus (as if it matters)…I always thought Harry Potter was kind of an ugly kid…that is until he sticks out his lower teeth in a smile.
Interestingly enough, one of the reasons I originally grew my goat-tee was becaue people were always telling me that I looked like Balky Bartakomus from “Perfect Strangers”. Now that the show has died down over the passage of the last ten years (or so), I’m contemplating shaving it again…
One girl once told me that I looked like Val Killmer as well before I shaved my goat. Perhaps she wanted me to ask her out…but I was young and inexperienced then. My response was, “Who’s Val Killmer?”
I was once told, many years ago when I was a lot younger and a bit thinner (before 2 kids), that I looked like Claire Danes. I couldn’t see it, but the person insisted and even dragged someone else into the room to look at me. The other person agreed with him. Of course, both of them were drunk so maybe that doesn’t count?
I also have a friend who looked, at the time, exactly like Leonardo DiCaprio. It was always amusing to walk around with him in public places when Titanic-frenzy was at its peak. He’d have teenaged girls following him in packs. 
I’ve gotten Sigourney Weaver. It’s the cheekbones or something.
I don’t know if anybody’s told her this, but I think one of our MinnDopers, Osbie, looks like a cross between Keri Russell and Nicole Kidman. Only shorter.
Ooooh, bjohn13! Val Kilmer and Harry Potter! My inner middle-schooler & my inner middle-aged woman are both excited!
Forgot that I also used to be told I look like Diane Keaton. After seeing Marvin’s Room I’m afraid it’s truer than ever.
Oh yeah, I get Dan Aykroyd a lot - fortunately, I am still somewhat thin, which can’t really be said for Mr. A.
I also get Jonathan Silverman a lot (I don’t have a goatee; he normally doesn’t, either) when he was on that sitcom right behind friends that was doomed to fail, The Single Guy
Most recently, I got that I looked like Mr. Big from Sex in the City. Other than a huge forehead, I don’t see it. Not that I minded the compliment.
I get both Keanu Reeves and Christian Bale a lot. I see the Christian Bale one a little more. I used to get Chris Cornell a lot; it eventually got creepy and I changed my hair and shaved off my facial hair.
I been told I look like Liz Hurley ( don’t see it myself) and someone from Emmerdale (the one who made album) I forgotten her name at the moment.
