The Marvel superhero film universe could grow as complex in terms of character density and continuity as the actual comics, it seems. Businessweek has a news story built around a new interview with Marvel Studios President Kevin Feige that hints at the thousands of characters Marvel has been discussing building various screen projects around, including those who will be introduced in the upcoming slate of films. Feige also talks about how forward-looking Marvel have become, with projects being bandied about at that would take the company up to as far as 2028. So far Marvel has nine superhero 'in-the-same-universe' movies out already, including the newly released Captain America: The Winter Soldier, and there are at least three more in pre-production. Later this year Guardians of the Galaxy will be released, followed in 2015 by The Avengers: Age of Ultron and then Edgar Wright's long-in-development Ant-Man. Marvel was bought for $4 billion by Disney four years ago.
