Fox's version of X-Men has already made significant claw marks in the hero film genre, but it's pretty exciting to think that Marvel now has an opportunity to revamp the franchise. Unfortunately, Hugh Jackman probably won't be returning as his iconic Wolverine character, and it's still unclear if Marvel will maintain the same actors for their presumed reboot.
In the comics, the X-Men are both friends and foes of the Avengers. Since we're gearing up for a new generation of Avengers in the MCU, this could very well mean the powerful groups will come face-to-face as either allies or opponents. And considering how many of the X-Men actually joined the Avengers team at some point in Marvel's glossy comics, there's so much potential for a crossover of cosmic proportions.
