Damages actress Rose Byrne is in talks to join Fox's X-Men: First Class, directed by Matthew Vaughn, reports The Hollywood Reporter.

With the plot kept under wraps, X-Men: First Class focuses on Marvel's superpowered X-Men team in a younger incarnation than seen in the previous trilogy.

Rose Byrne will play Moira MacTaggert, a scientist and an authority on genetic mutation. She'll be the love interest of James McAvoy, who plays mutant telepath Charles Xavier.

Fox will film in London at the end of this month.
