Re: Ideas on how to achieve time travel
I don't imagine Gateway appearing in any of the X-Men movies. I see a mutant from the future (Beast or Forge or Cable - if they don't want use to Forge and Beast) creating a time machine to go back to the past. I hope time travel wouldn't sound and look complicated, just make it simple and direct like the time travel of the TV show Heroes. I feel like alternate universe is too early for the X-Men movies.
