For example: Natalie Portman and Keira Knightley. Knightley quickly replaced Natalie Portman as Queen Amidala’s bodyguard in Star Wars Episode I: The Phantom Menace.
Pamela Anderson wasn’t as unique in her Baywatch role as one might think either, Donna D’Errico was a perfect replacement for the world’s most famous lifeguard.
Actresses Courtney Cox and Demi Moore are not only good friends, they could easily be twins.
Hollywood superstar Javier Bardem and “Grey’s Anatomy” actor Jeffrey Dean Morgan also look alike. They really are almost indistinguishable from each other. Will Ferrell and “Red Hot Chili Peppers” drummer Chad Smith took part in “The Tonight Show”. Jimmy Fellon even made fun of their resemblance and appeared in a partner look.
