Peter Dinklage joins X-Men: Days of Future Past as the main bad guy

Over the past couple of months we've seen plenty of familiar faces signing on to reprise their roles in Bryan Singer's X-Men: Days of Future Past, and now the film has secured its first newcomer to the X-Men universe with Singer revealing via Twitter that Game of Thrones star Peter Dinklage hasjoined the cast of the forthcoming mutant sequel.

While early speculation leaned towards Dinklage playing the character of Puck, a super-powered dwarf and member of the Canadian superhero team Alpha Flight, Variety is claiming that the Golden Globe-winner will instead portray the film's primary antagonist. Of course, with the film set to incorporate time travel, it's unclear whether the main bad guy will feature in the 1970s, or the alternate future where Sentinels rule the United States.

X-Men: Days of Future Past is set to start shooting on April 15th, with an impressive cast that includes X-Men: First Class stars James McAvoy (Professor X), Michael Fassbender (Magento), Jennifer Lawrence (Mystique) and Nicholas Hoult (Beast) alongside original X-Men trilogy veterans Hugh Jackman (Wolverine), Patrick Stewart (Professor X), Ian McKellen (Magneto), Ellen Page (Kitty Pryde), Anna Paquin (Rogue) and Shawn Ashmore (Iceman).
