After teasing a select few fans and journalists with some footage at Comic-Con back in July, Marvel and Fox finally dropped the first official trailer for X-Men Apocalypse, the third film in director/producer Bryan Singer’s young-mutant trilogy. (It’s the 9th X-Men movie overall.) This time around, the mutants face their biggest adversary yet: the godlike, original mutant Apocalypse, played by Oscar Isaac, who is recognizable underneath all that CGI.
