Although it is indicated in X2 (2003) that his character (Senator Kelly) is at least 20 years younger than Brian Cox`s character (William Stryker), in real life, he is only 27 days younger.

Director Robert Aldrich gave advice to Davison when he was starting out as an actor. "Be a character actor. Hero or villain, character actors always work.".
