John F Kennedy is the President of the United States. Martin Luther King and Malcolm X are on TV doing marches. There is a spirit of a hopeful future that was prevalent in that time. We will see how Xavier and Erik Lehnsherr met - and how they dreamt of a future with Mutant & Human kind. They're going to be in their late twenties. Xavier - as played by James McAvoy will not be in his wheelchair to begin the film - but we will see how he wound up in a wheelchair.The characters will wear more traditional comic book costumes than the type seen in Singer's X-Men films. Director Vaughn is also very inspired by the gadgetry and technology used by James Bond in the original 60's films.
Kevin Bacon will be playing Sebastian Shaw the leader of "The Hellfire Club," an inner Circle of influential entrepreneurs, politicians and socialites whose desire is to achieve world domination through political and economic influence, subversive activities and the recruitment of mercenary forces and powerful superhumans.
The movie will have a more international feel than the prior X-Men movies and will be shooting in England & the United States as well as representing other territories around the globe with one of them being Russia (The Soviet Union).
Singer also revealed that Cyclops and Jean Grey won't feature, but that his brother Havok will appear played by Lucas Till. Nicholas Hoult will be Hank McCoy AKA Beast, Rose Byrne is playing Moira MacTaggert and January Jones will now portray Emma Frost.
