6. Keep The Pace Up From The Outset
While the X-Men was a hugely successful ensemble film that paved the way for all subsequent superhero movies, fan expectation was literally insane prior to the release of Avengers Assemble. The entire project was arguably one of the most ambitious cinematic undertakings of all time, as never before had so many iconic characters been brought together in one movie. Luckily, Marvel's gamble paid off in a huge way, due in large part to a fantastic script, intelligent direction and strong performances across the board. Truthfully though, the movie could have been distinctly average and many lifelong comic book fans would have still experienced a thrill just seeing Marvel's flagship team finally on the big screen together, almost fifty years after they first appeared in The Avengers #1. However, many fans complained that it took too long for the Avengers to actually unite within the film itself. Arguably, it was necessary to establish a number of plot threads before the team could be assembled, but in contrast to the second two acts, the first forty-five minutes felt much slower in comparison. This should not be a huge issue in Avengers: Age of Ultron, as the team dynamics have now been established for audiences who are more than familiar with these heroes. The only way a slow build up could occur again in the sequel depends on how Whedon introduces the new characters Quicksilver and his sister the Scarlet Witch. It would be impossible to keep up a consistently fast pace for every second of the film and it certainly would not be satisfying to watch, but Whedon would do well to bear these potential pacing issues in mind while shooting his script.
