We all know him as the lovable bastard on Game of Thrones (who should have taken a roll in the snow with Ygritte (Rose Leslie)), but Kit Harington may soon lend his voice to a more villainous character.  Harington is up for a role in DreamWorks Animation's How to Train Your Dragon 2.  The sequel to the 2010 hit features the return of Jay Baruchel, Gerard Butler, America Ferrera, Christopher Mintz-Plasse, Kristen Wiig, Craig Ferguson, T.J. Miller, Jonah Hill and more in the vocal cast, in addition to the fine assortment of scaly beasts on screen.  Hit the jump for more on this potential casting addition.Variety reports that Harington is in negotiations to voice an antagonistic warrior in the How to Train Your Dragon sequel.  The second iteration sees the return of co-writer and co-director Dean DeBlois who will write and direct once again.  Previous co-writer and co-director Sean Anders will executive producer with DeBlois, while Bonnie Arnold returns to produce.  How to Train Your Dragon 2 is set for a June 20th, 2014 release date.  Few details have been released for the second part of a planned trilogy based on the best-selling books by Cressida Cowell. Between now and then, you can see Harington (who also landed a role opposite Vera Farmiga in Greenland Time) in Silent Hill: Revelation 3D when it debuts October 26th of this year.  Harington also just wrapped up filming a supporting role alongside Jeff Bridges in Disney's The Seventh Son, which will debut on October 13th of 2013. Perhaps you can get a look at Harington when Game of Thrones comes to Hall H at Comic-Con 2012.  Other than that, we'll have to wait until the epic HBO series returns next year.
