The marketing for X-Men: First Class has been kind of interesting, largely because it’s being produced on such a tight schedule that while blockbusters normally sell themselves on their effects, First Class hasn’t had as many of those ready, so it’s tended to be more talky than normal. Now two new trailers have emerged – a US and international one – which are still fairly talky, but do show off quite a lot more of the scale of the flick. The two trailers are fairly similar, but there’s enough different footage to make it worth watching them both. James McAvoy and Michael Fassbender star as young versions of Charles Xavier (Professor X) and Erik Lenscherr (Magneto), who were friends before becoming enemies, and as this trailer shows, had a lot to deal with in the 60s, when a new species of mutants was emerging and the world was on the precipice of nuclear war.
