We all know where this is going: Professor X and Magneto will one day be the deepest enemies. How they get to that point is the story told in "X-Men: First Class," and if the first trailer is any indication, how they get there is going to be totally badass.
This is an origin tale, after all, as the trailer makes clear. The footage begins with an appropriately edgy, slow-building score in the background, then a shot of Professor X's office, with his empty wheelchair in the foreground. The words "Before he was Professor X" appear over a shot of what looks like Patrick Stewart as X, hooked up to Cerebro, then, continuing the first phrase, the words "He was Charles" are shown over a shot of James McAvoy as our young Chuck Xavier.
The next sequence opens with "Before he was Magneto" over shots from previous "X-Men" films and Ian McKellan wearing the famous helmet and cape, then "He was Erik" over a clip of serious/brooding Michael Fassbender as young Erik Lehnsherr.
Cut to Marvel's recognizable movie insignia, the shuffling comic book pages with the logo, followed by McAvoy's Xavier and Fassbender's Lehnsherr walking together in a prison. The next clip shows the famous "School for the Gifted," with the words of JFK speaking to the Cuban Missile Crisis in the background and the rest of the cast/X-Men crowded around the television listening to Kennedy's televised address.
Next up we get brief character intros, with JFK's words — "The cost of freedom is always high" — still echoing in voice-over as Emma Frost (January Jones), Angel Salvadore (Zoe Kravitz), Hank McCoy/Beast (Nicholas Hoult), Alex Summers/Havok (Lucas Till), Moira MacTaggert (Rose Byrne) and saucy shape-shifter Mystique (Jennifer Lawrence) all flash in succession onscreen.
The last half of the 1:51 spot kicks up the action, with shots of fighter jets (Beast in the cockpit!), missiles launching, young mutants learning how to use their powers to fight and Lehnsherr taking hold of the famous helmet and stepping into the black-and-red suit of Magneto, followed by stern words from Xavier.
"Listen to me very carefully, my friend," Xavier says to Lehnsherr/Magneto. "Killing will not bring you peace."
"Peace was never an option," he responds, which is followed by quick teases of some of the big action scenes, including one where Lehnsherr is pulling a submarine out of the water and into the air.
The last thing we see is a revamped and slightly imposing logo for "Xavier's School for the Gifted Youngsters," First Class, followed by the June 3 release date.
