Here's the first proper trailer for X-Men: Apocalypse, the third and final instalment in its X-Men: First Class movie series. Professor X and Mystique lead the team of X-Men to stop the immortal mutant Apocalypse from destroying mankind. There are loads more mutants to entertain you including a young Jean Grey played by Sophie Turner from Game of Thrones doing a pretty terrible American accent but hey, don't let that put you off.
