In the wake of The Avengers, movie franchises have aimed for larger scales and the combining of movie casts. The Fast & Furious franchise folded in Jason Statham’s Transporter character with the closing scene of Fast & Furious 6. Man of Steel is begetting Batman v. Superman: Dawn of Justice, which is ultimately begetting a Justice League movie.
Not to miss the boat, the X-Men franchise delivers their attempt at a combined hero action movie, X-Men: Days of Future Past, which unites the cast of the 2000-2005 X-Men trilogy and the cast of the 2011 prequel-boot X-Men: First Class. Gloriously, X-Men: Days of Future Past is many things at once — a combined hero action movie being just one of them — and succeeds on all fronts.
