Avengers Assemble is the most successful Marvel film to date, no question. The entirety of Phase 1 was essentially one giant plan to bring Earths Mightiest Heroes together, and the result succeeded wildly beyond anyones expectations. So much could have gone wrong, yet Joss Whedons first foray into the world of Marvel movie making is loved by the vast majority of fans and from the studios point of view, its also made more money than any other film thats not been directed by James Cameron of course. Marvel is set to repeat this success again with the release of Avengers: Age of Ultron in 2015 , so it makes sense for DC to consider emulating this approach in the formation of their own cinematic universe. Plans are already set in motion to phase new characters into the upcoming DC films to prepare for the release of the Justice League of America, a team that combines all of the companys most popular properties into one group. Heres where it gets really exciting though. The Avengers may be Marvels premier team, but some of the companys most popular characters such as Wolverine and Spider-Man are unlikely to ever share the big screen with them due to legal rights. On the other hand, DCs Justice League of America could potentially feature every single one of the companys heavy hitters in one movie. Superman, Batman, Wonder Woman, Green Lantern, the Flash, Aquaman, Martian Manhunter the list is endless. For fans of DC comics, this movie could literally be a dream come true and if there is one movie that could conceivably eclipse the success of the Avengers franchise, then its the JLA.
