Then again, a hypothetical Marvel / Fox crossover might also be pushed so far into the future that few of the original cast members of the Marvel Cinematic Universe and Bryan Singer’s X-Men series will still be around.
If Marvel and Fox are indeed finding a common ground, this can only mean bigger and better things for the MCU.
Not to be outdone, rumors have emerged that 20th Century Fox might have similar plans for their X-Men characters.
As for possible storylines, since Marvel Entertainment has skewed towards recent comic book plots in their film adaptations, one possible outcome could be the 2012 Avengers vs. X-Men crossover event.
