But the wheels are still turning, apparently, as TheWrap has learned of Warner Brothers' extensive wishlist for the role that would've been opposite Clooney. The three main names being considered are Joseph Gordon-Levitt, Ryan Gosling, and Alexander Skarsgard. The first two are pretty easy as they'll appear on everybody list for every movie. The kicker is Skarsgard, who most will recognize as Eric Northman on HBO's True Blood. While his big screen presence remains fairly untested, he's got a lot coming up. He stars in a remake of Straw Dogs which is out right now. He has a minor role in Lars Von Trier's disaster pic, Melancholia, and next year will be featured in Peter Berg's Battleship. None of those would likely make Skarsgard the movie star a film like U.N.C.L.E. would.
The same could be said of Gordon-Levitt and Gosling. I doubt either of them has the time to fit in a film that by all accounts is going to be physically taxing and action heavy.
Soderbergh's frequent writing partner, Scott Z. Burns(Contagion, The Informant!), wrote the script, which will keep the same action/comedy tone and will be set in the 1960s.
