Fox's 'X-Men' franchise and Disney's MCU haven't crossed over yet, but Ryan Reynolds is for it!

The 'Deadpool' star asked 'Guardians of the Galaxy' director James Gunn to do a crossover.

It began when Gunn tweeted about finally seeing Deadpool 2 and loving it.

Reynolds replied, thanking the director for his kind words and asked for a crossover.

Gunn did not seem against the idea. So we'll see if that comes to fruition.
