Over the years, I have gotten Ice Cube(eyes/eyebrows only), Daunte Culpepper, and recently Aries Spears.
I resemble none of these people. If anything, I look like Star Trek Alternate Universe Carlton(if he existed).
A couple of months ago I had someone tell me I look like Matt Damon… I’m still not sure how…
My brother also bears a striking resemblence to Ashton Kruchter (sp) (Kelso from That 70’s Show). Especially amusing since he (my brother) lives in Los Angeles. We were once at the beach in Santa Monica when some random chick ran in front of us, took a picture, and ran off without saying a word.
And it never hurts to have the ladies in the bar think you’re there with a celebrity 
If any celebrities look like me, I pity them.
I look like Cher and Frank Zappa had a baby.
When I have bangs, I look a bit like Tina Yothers back in her “Family Ties” days.

I’m sorry for being shallow, but that made me laugh. Not the Val Kilmer bit. That’s actually a good thing.
No, I don’t look like any celebrity.
Carry on, carry on.

Mary Louise Parker
and the girl from Blair Witch
Dunno - Who do you think I look like? I’m the one on the left. My hair is short now, but other than that I’ve not changed. I don’t think I resemble any celeb.
Snoop Dogg
Unfortunately, people tell me at least once a week I look like Brittany Murphy… I’ve actually had strangers actually stop me on the bus and street and tell me this…
When my hair was longer someone told me I looked like Darryl Hannah. Now my uncle is convinced I look like Julia Stiles.
Ohhhh, baby. Leave it on.
As anyone who has ever met me will tell you (I’m looking at you, Gundy. For confirmation. Well, I’m looking at you, too. But that’s for my own personal use later ;)), I look EXACTLY like John Mellencamp and Mike Myers had a child.
Ask anyone who has ever taken a picture at a ChiDope, OhDope, or the NYC Dopefest I attended last January (2002, that is).
I get told that I look like Ray Liotta a lot. The first few times I was flattered, but then its gets annoying. Its like having a cast & people asking you how you broke your arm.
Now, whenever anyone says "hey, you look like Ray Liotta, I give them the classic ‘Ray Liotta staring smile’ and move toward them, invading their personal space. Its amazing how this Really starts to freak them out ( Must be they’ve seen ‘GoodFellas’ one too many times…go figure).
The best is when they walk off muttering ‘F-c-ing Actors…!’
“Stone Cold” Steve Austin.
Or a recently paroled/escaped convict.
I’m still not quite sure which is the compliment and which is the insult.
Jack Black, I get that one all the time, though very often it’s from drunk people at bars.
Apparently I look exactly like Toby Macguire in Spiderman. All of the teenage girls that I work with call me Spiderman now. The “after spiderbite” Peter Parker, not the before! 
I’ve been told by a few friends and complete strangers that I look like a younger Clint Eastwood. My wife, alas, does not see it. 
Apparently a lot of people think I look like a cross between Johnny Depp and Steve Buschemi. I’m really not sure what to think about this.
But my cousin and a few other people swear I look like Jon Davis.
I happen to think I look tired and grumpy.
