Two supporting characters from X2: X-Men United will be in the Fantastic Four movie, producers told the press recently.
In a publicity photo released from the film, Victor Von Doom (Julian McMahon) meets and shakes hands at the White House with William Stryker (Brian Cox) and Senator Kelly/Mystique (Bruce Davison). Instead of shooting the new scene, FF film director Tim Story will have McMahon digitally replace President McKenna (Cotter Smith).
In X2, Franklin Richards' name appeared on a screen of suspected mutants in Stryker's database.
