Well, it's confirmed. There is a sequel to X-Men: First Class and the Matthew is back as the director.
My favorite movie/TV blog, Deadline stated:
Fox has just closed a deal with Matthew Vaughn to come back and direct the sequel to X-Men: First Class, with Simon Kinberg writing the script and Bryan Singer back as producer.Okay, I can deal with this. However, I want the original team back in the mix; maybe add Lorna/Polaris and Mimic as well. Also, I hope they won't mess the timeline any further. These X-stories are out of control.
Still, I think it will be a decent product. The last movie was good.
