Our Russian comrades over at Stark Industries have obtained information which may have revealed the title of Matthew Vaughn's X-Men followup. Russian News site Film Business Today states that the sequel will be lifted from the pages of Marvel comic books and will be called X-Men: Days of Future Past. Fox envisioned X-Men: First Class as the first film of a new trilogy.
