3. Cast a Great President
Obviously, Bill Pullmans President Whitmore wont be in office anymore, but every good American disaster movie needs a good Commander in Chief, especially since its likely that hell become an important piece of the plot. Spare Morgan Freeman and Danny Glover the role, theyve both served their time as Head of State during a world wide calamity. Instead, if I had my say, Id take the best part of Emmerich's 2012 and throw him into the Oval Office. Thats right: Woody Harrelson. Hes got the comic timing to work with the rest of the cast, but can play serious too when he has to. Hes done politics successfully before in Game Change, and while you dont really need that on your resume to play Head of State in a Roland Emmerich movie, it doesnt hurt. The film needs a great president regardless, but if Im Emmerich or Devlin, Im voting Harrelson into the role.
