Last summer, British filmmaker Edgar Wright (Shaun of the Dead, Hot Fuzz) screened some test footage from his long-in-development Ant-Man adaptation at the San Diego Comic-Con International. Since then, the footage has been kept firmly under lock and key, but now it has finally arrived online after being shown at the Best of BUG event in London this week, where one audience member just so happened to have their camera phone at the ready. You can check the footage out here, but be quick - I imagine Disney's legal department is going to be working overtime today to get these videos taken down...
Ant-Man is currently scheduled to kick-off Phase Three of the Marvel Cinematic Universe when it hits cinemas on November 6th, 2015.
