According to EW.com, that actor is Armie Hammer, who played both Cameron and Tyler Winklevoss, the twin brothers who claimed they were ripped off by Mark Zuckerberg (Jesse Eisenberg), in David Fincher's 'The Social Network.' EW.com also reports that the title of the movie has been changed to 'J. Edgar.'
Meanwhile, MTV is reporting that Charlize Theron has been offered the role of Justice Department file clerk Helen Gandy, who worked with Hoover for more than 50 years.
Theron has been kind of quiet the last couple of years, but she has 'Mad Max: Fury Road' coming out down the road and has been rumored for the next Batman movie, 'The Dark Knight Rises.'
Thanks to the shadings provided by Hammer, the Winklevoss twins may have looked the same but they were not identical in their reactions, which may have led some viewers to conclude that real-life twin brothers played the parts. (As explained at EW.com, Hammer played one twin during filming, while Josh Pence stood-in for the other twin; later, Hammer's face and voice replaced Pence's.)
And, speaking of Batman, as were about Theron, Hammer was cast as Batman in George Miller's proposed 'Justice League,' which never got to the starting block. Hammer continued to work mainly in television ('Gossip Girls,' 'Reaper') until 'The Social Network' provided him with a breakthrough opportunity. He nailed the performances, making you somewhat sympathetic to the plight of the twins -- bearing in mind that they walked away with a reported $65 million settlement.
In any event, Hammer now looks poised for bigger things; scoring a key role against Leonardo DiCaprio as J. Edgar Hoover, romance or no romance, would be a great start.
