Warning: Spoilers
Eric Dane (pictured), a one-time regular on the WB's Charmed, is slated to play Jamie Madrox, the Multiple Man in X-Men 3, according to X-MenFilms.net.
According to the fan site, the actor is working with about 50 stunt doubles and his character is allied with Magneto's Brotherhood as a part of Omega Red's faction.
Meanwhile, more set pictures from British Columbia are online
here. The scenes appear to be at the Golf Club Drive in Tsawwassen, South Delta and probably involve a flashback sequence to when Magneto and Professor X first met Jean Grey (younger version played by Haley Ramm).
