Natalie Portman and
Keira Knightley were considered for roles in Disney's remake of
The Parent Trap, but they were rejected because even identical twins have
some differences. (In this morphed
photo, Natalie's face is on one side, and Keira's face is on the other. Can you tell them apart?)
Lindsay Lohan ended up starring in
The Parent Trap, only to be criticized for being too one-dimensional to play two roles. (Thanks, June!)
