Sean Teale, fresh off the canceled Syfy series Incorporated , will play Marcos Diaz/Eclipse. A natural rebel compelled by circumstances to cooperate with others, Marcos is a passionate and strong-willed fighter who sometimes lets his emotions overrule reason. His alter ego, Eclipse, who possesses the ability to absorb and manipulate photons, is a newly created mutant for this expanded X-Men universe. Teale also joins previously cast Blair Redford and Jamie Chung.
The still unnamed Fox show written by Matt Nix and directed by Bryan Singer, the pilot focuses on two ordinary parents — the dad played by Moyer — who discover their children possess mutant powers. Forced to go on the run from a hostile government, the family joins up with an underground network of mutants and must fight to survive.
