How to tell these often mixed up celebrities apart.

Jakov Smirnoff
F. Murray Abraham

My own lookalikes:

Minka Kelly and Erinn Hayes

Kerry Bishe and Marin Ireland, but not when they smile so it’s hard to find examples.

Teresa Palmer and Amber Heard

Amber Tamblyn and Brittany Allen

Now I always got Jan Smithers (Bailey Quarters) confused with Marcia Strassman (Julie Kotter)

Will Patton - General Bethlehem
Bill Paxton - was in Agents of SHIELD

OK, I confused them.

Bill Pullman - Daryl Zero, the Prez in Independence Day, and “Mr. Wrong”
Jeff Daniels - in Dumb & Dumber and The Newsroom.

Actually, I’m not sure I confuse the two of them so much as I keep thinking there’s a third one of them somehow who does the dumb comedies.

I still get Nick Nolte and Gary Busey mixed up. Grizzled crazy white guys all look alike.

Bill Paxton: Usually has short hair with no part.
Bill Pullman: Usually has longer, poufy hair with left part.

Bill Paxton: Earlobes
Bill Pullman: Earlobes

from Sesame Street:

Cookie Monster: blue, wants cookie
Oscar the Grouch: green, in garbage can
Grover: blue, not wanting cookie or sitting in garbage can
For years I had only a black & white television and would get these three mixed up. I never saw Sesame Street as a child, I was grown before the show started.

Scooby Gang: But the true owner of the haunted WKRP and Kotter sitcom sets is…tears off mask
Everyone: Pam Dawber!
Pam: And I would have gotten away with it if it wasn’t for you meddling kids!

Same with me. I think I’m becoming a grizzled crazy white guy…wonder if I look like Nick Busey myself?
