To coincide with the DVD and Blu-ray release of this year’s biggest comic book movie – Avengers: Age of Ultron, of course – we thought we’d take a look back at the Marvel Studios offering and reflect on how it could have been better.

Don’t get us wrong, it was a great movie and rightfully smashed it at the box office – pulling in $1.4 billion, it currently sits as the third highest-grossing movie of 2015 (behind Jurassic World and Furious 7) and the sixth highest-grossing movie of all time (behind Avatar, Titanic, Jurassic World, The Avengers and Furious 7) – but the more we look back on it, the more we realise it might not quite have lived up to its hype.

So what could have been done to improve it? Well, there are a number of things, but one of them could have been to include certain characters who were missing from the Marvel Cinematic Universe movie. This article will list five of them who would undoubtedly have made it better.

Hank Pym

In Avengers: Age of Ultron, it was Tony Stark (with a little help from Bruce Banner) who inadvertently created the evil robot Ultron. In the comics, however, it was Hank Pym.

An older version of Hank Pym is being played in the Marvel Cinematic Universe by Michael Douglas – and he didn’t actually appear in the franchise until Ant-Man, which came after Age of Ultron, but it would have been a nice nod to the comic books (and something for the fans to acknowledge) if he had at least made a cameo in the Avengers sequel.

Having Tony Stark consulting Pym over the building of Ultron and subsequently seeing Pym telling him it was a bad idea would be a funny Easter egg to have included – and one that would have given the movie that little bit of something extra.
