The Marvel Cinematic Universe is huge, and dominates Hollywood like few things before it. Once a past-time open for ridicule, the characters of comic books now find themselves with a stranglehold on the movie industry The Avengers holds the crown as one of the highest-grossing movies ever, and Marvel can sit back safe in the knowledge that a whole bevy of A-listers are signed up to don the spandex in their most famous roles. With this in mind, it's no wonder that Marvel Studios President commented earlier this week that they feel safe enough to plan movies all the way up to 2021. Such an announcement is interesting enough in itself, but seeing as we only know of definite films going up to 2015, culminating in Phase Three opener Ant-Man directed by Edgar Wright there's going to be a few gaps Marvel will have to plug on their film release schedule, and they can't fill them with the Avengers A-team alone. This means there's a need for new superheroes, and being fair, Feige has acknowledged this, hinting at numerous properties he hopes to see make it to the big screen. Yet what's more interesting is that Phase Three will feature a moving of tact by the studio, as they look to bring up the more obscure heroes with slightly cheaper flicks. Of course, what's cheap to Marvel most definitely isn't to others they're still thinking of investing up to $40 million dollars in 'minor' properties. It's with this in mind that this list was created, as I've taken characters Feige has hinted at adapting and hopefully come up with the perfect actor to play the part. Yet before you go on, I must point out that I'm not a time-travelling sorcerer, so obviously these superheroes are not in order, they're just the heroes Feige seems to want to adapt. With that sorted, let's begin!
