EXCLUSIVE: WME has signed writer/director Dan Harris, who’s currently scribbling X-Men: Apocalypse with Michael Dougherty and Simon Kinberg for director Bryan Singer. Harris, who’d been repped by CAA, moves over to the same agency that reps his often writing partner Dougherty, with whom he worked on Fox’s X-Men 2 and Warner Bros’ Superman Returns. Singer, who directed both those films, is also at WME. Harris continues to be lawyered by Loeb & Loeb.
