Michael Fassbender is officially on board to play bad guy Magneto in "X-Men: First Class."

Benjamin Walker, meanwhile, has closed his deal to portray Henry McKoy, aka Beast.
Fassbender was being courted for villain roles in Fox's relaunch of the "X-Men" franchise, directed by Matthew Vaughn, and Columbia's relaunch of "Spider-Man." He entered talks with Fox two weeks ago.
The studio is in full-blown casting mode for the movie, which is gearing up for an August start in London, and is in the process of filling out its cast of young mutants.

Fassbender will join James McAvoy, who is playing Professor Xavier in the pic, which focuses on Marvel's superpowered team X-Men in a younger incarnation than the previous trilogy.
It is unclear at this time which incarnation of the Beast character Walker will portray in "First Class." In X-Men lore, Beast was originally an oversized young man with gorilla reflexes and a superior intellect. Later, he morphed into a blue-furred, tiger-like humanoid.
Fassbender's big Hollywood break came with a key turn in "Inglourious Basterds," in which he played Canadian spy Archie Hicox. The actor, repped by CAA and Troika in the U.K., stars in Neil Marshall's Roman action movie "Centurion," which opens in August.
Walker, repped by WME, appeared in "Flags of our Fathers."
