User blog comment:Mark4518/X-Men’ Producer Would Love An ‘Avengers’ Movie Crossover/@comment-3317214-20130219142212

If Days of Future Past creates some way to deal with the baggage that comes along with X-Men, then I would love this to work. Especially because it means that the FF would be included as well, as part of Fox's Cinematic Universe.

Also, Mark Millar has also stated that he would love for all the Marvel films to feel like they're coming from the same place. For Spider-Man, the Avengers and the X-Men to feel connected.
