Jesse Eisenberg and Ashton Holmes: Separated at Birth?

Sept. 15, 2010— -- Did you catch Jesse Eisenberg in last week's premier episode of CW's new series "Nikita"?

Oh, wait a minute. That wasn't Eisenberg, the 26-year-old actor who starred in "Zombieland," "Adventureland," and plays Facebook founder Mark Zuckerberg in the widely-anticipated movie "The Social Network."

On "Nikita," the actor who plays Thom, a recruit assassin, is 32-year-old Ashton Holmes, a dead ringer for Eisenberg. Five years ago Holmes played the son of Viggo Mortensen in "A History of Violence." More recently, he portrayed a soldier in HBO's Emmy award-winning miniseries "The Pacific"
