Former Doctor Who, Christopher Eccleston, is to star in 'Thor: The Dark World'.
The 48-year-old actor is in final negotiations to play super-villain Malekith the Accursed in the follow up to the 2011 superhero movie, which sees Chris Hemsworth portray the titular character and is to be helmed by 'Game of Thrones' director Alan Taylor.
Malekith, the ruler of the Dark Elves of Svartalfheim, is expected to go up against Thor in the forthcoming movie as he does in the Marvel Comics, but plot details are largely being kept under wraps, Deadline reports.
It's not the first time Eccleston has portrayed a villain after previously starring as weapons designer Destro in 2009 action movie 'G.I. Joe: Rise of the Cobra' alongside Channing Tatum and Sienna Miller.
Christopher also took on a bad guy role in 2002 motion picture '28 Days Later' and NBC sci-fi TV series 'Heroes'.
In May, Hemsworth admitted he was "nervous" about starring in 'Thor: The Dark World' – which will also feature Natalie Portman and Anthony Hopkins - because he was yet to a script.
He said: "'Thor 2'? Yeah I start shooting in August. I haven't seen a script yet which makes me nervous but yeah! Alan Taylor is directing who has done 'Game of Thrones' so it should be good."
'Thor: The Dark World' is scheduled for release in November 2013.
