New cast members of the third X-Men movie include Olivia Williams (The Sixth Sense, pictured) as Dr. Moira McTaggert, Michael Murphy (Gotham's mayor from Batman Begins) as Warren Worthington, Jr. (Angel's dad) and, as previously reported here, Bill Duke (Predator) as a "politician in the President’s cabinet," according to IGN Filmforce. We heard he was Dr. Trask, creator of the Sentinels, but IGN claims that's wrong.
