Peter Dinklage X-Men villain confirmed?

It seems we're edging ever-closer to finding out just who Peter Dinklage is playing in the forthcoming 'X-Men' movie, 'X-Men: Days of Future Past'.

While it's not officially confirmed, the latest picture from director Bryan Singer provides us with the most substantial - but still tantalising - clue yet.

Tweeting from the set, Singer snapped the jumpsuit of a gent grabbing his lunch from the craft service table. It is emblazoned on the back with 'Trask Industries', what would appear to be the company of Bolivar Trask.

From the 'X-Men' universe, Trask is an anthropologist and military scientist who believes the mutant X-Men to be a threat to humanity. He creates the Sentinels, robotic 'guardians of humanity' to destroy the mutants.

Speculation has been rife over who the 'Game of Thrones' star will play, with talk initially surrounding Puck, the diminutive Marvel Comics hero.

But it since emerged that he would be playing the film's main villain – leading most to the conclusion that Trask was the most likely character.

Now it seems that it could be all but confirmed that Dinklage will be Trask, bar a statement (or more likely a tweet) from Singer himself.

Whoever Dinklage is playing, he's in A-list company.

He will be sharing screen time with Sir Ian McKellen, Sir Patrick Stewart, James McAvoy, Michael Fassbender, Hugh Jackman, Halle Berry, Anna Paquin, Ellen Page, Shawn Ashmore, Jennifer Lawrence and Nicholas Hoult.

'X-Men: Days of Future Past' is out in July, 2014.
