Think back, have you been told that you resemble a famous person? I have.
BEST: Mariah Carey 
WORST: Roseanne Barr :eek:
I’ve been told many times that I look like Jamie Lee Curtis.
Many people have said Jeff Bridges looks like me.
I have been mistaken for Dr. Demento repeatedly at conventions. Granted, I was wearing a tuxedo and top hat at the time.
Johnny Depp (when I had a beard), Jack Black (when I didn’t).
It’s important to note that these comparisons were made by drunk people.
No one has ever likened me to a celeb. I have a friend, tho, who’s a dead ringer for Liam Neeson!
Best: Ed Helms
Worst: Fred Gwynne
I’ve gotten Ed Helms quite a bit recently, but that’s probably just because these kids today don’t know Fred Gwynne.
Random strangers will tell my fiancee she looks like Jennifer Garner.
I was repeatedly told I looked like Paul McCartney when I was younger. I haven’t been told that since I hit the big 4-0. I suppose either Paul or I have not aged well. 
Johnny Knoxville
I’ve been told many times that I was a dead ringer for baseball player Keith Hernandez. Not sure how much of a celebrity he counts as, since he hasn’t played in years, though he was on Seinfeld a few times.
Best: Omar Shariff (when we were both much younger).
Worst: Dennis Franz (with a little more hair on top, plus a goatee).
Larry Bird.
But only by black guys.
As my BIL says, “They can’t tell us apart either.”
That just reminded me…I get Tony Robbins a lot, too.
An artist I modeled for as a young teen said I looked like a Titian painting.
More recently, lots of people (I work at a public service desk) have told me I look like the Ruby Sparks actress Zoe Kazan.
The first was flattering. The second I actually somewhat can see the resemblance.
Anthony Edwards
I have heard Liev Schreiber and Mark Wahlberg both from my wife, and Michael J. Fox from her mother.
My retort when I hear “You look just like…” is invariably
“No, he looks like ME.”
Not so much now, but when I was in high school, I looked a bit like Alan Ruck (Cameron from Ferris Bueller’s Day Off.) Looking at some pictures of him now, though, there is no resemblance. He’s aged a bit better.
I have been told Elaine Irwin and Sienna Miller- but I don’t see the resemblance at all (these ladies are both gorgeous and while flattering…COME ON) and I suspect these people were hammered or perhaps have very compromised eyesight.
I am also older now, so no one recently.
Gary Sinise. Except he obviously dyes his hair.
