Sony’s ‘The Amazing Spider-Man 2’ has a mid-credits sequence featuring 20th Century Fox’s ‘X-Men’.
The credit sting features Jennifer Lawrence as Mystique battling a young William Stryker in an army barracks alongside a host of other mutants including Toad and Havok played by Lucas Till.
It’s an action-packed sequence that ends with a plane taking off. We presume this is the Vietnam-set section glimpsed in one of the trailers.
