I know this may seem like a very stupid idea but honest i think it could work if it was done properly. It would be a very intresting take on the X-Men Universe so it could work..
Cyclops/ Karl Urban
I would go with a older Cyclops for this film. Someone who is a fantastic actor and could pull off Cyclops well..i loved Judge Dredd so why not give Karl Ubarn a change..sure some people would argue he is a bit too old but i for this reboot i wanted the charcters not to bee teens or young adults so it works
Beast/ Stephen Fry ( Voice)
For Beast you need someone who has weight to his voice while also sounding smart and sophiscated..Stephen Fry is your man for that. He would lend the perfect voice for Beast. It would be similar to Rocket Raccon while Stephen Fry would lend the voice but but Beast would be CGI
Dwayne Johnston / Colousses
Is he the greatest actor in the world..No but for playing a charcter lie Colousses he is perfect for the role. He would easily be able to bring the strangeth and have some kick ass action scenes...
Emma Stone/ Jean Grey
I know this is a bit on the unlikely side but come on she would be a great Jean Grey. She is attractive but still is a great actor who could easily hold out on her own in the Battlefield.
Part 2 is coming soon..
