X-Men: Days of Future Past features the biggest ensemble of mutants put together on film to date as both the original cast and the newer cast from X-Men: First Class join together to fight a war for the survival of both human and mutant kind across two time periods. When the future war between mutant/mankind and the treacherous sentinels near its darkest hour the small but steadfast group of X-Men still alive –Professor X (Patrick Stewart), Storm (Halle Berry), Wolverine (Hugh Jackman), Magneto (Ian McKellen) – meet up with former students Kitty Pride (Ellen Page), Iceman (Shawn Ashmore) and their compatriots to form one last ditch effort to save all their lives. Wolverine is sent back in time to join the then rival Charles Xavier (James McAvoy) and Magneto (Michael Fassbender) together to stop the events that lead to the mass destruction to come.
The star studded cast also brings backs Jennifer Lawrence as Mystique and introduces Peter Dinklage as the man responsible for the sentinels, Bolivar Trask. Director Bryan Singer manages to coordinate all of this chaos into a complex yet balanced story that features the entire mutant cast getting enough exposure that they are not wasted while still feature the few that audiences really want to see. The film also packs some effective twists and some memorable cameos from other mutants that will delight audiences. The script ingeniously leaves room for multiple follow ups involving either cast and manages to reset the entire mutant universe in one shot.
