Michael Douglas has been cast in the upcoming Marvel movie Ant-Man.

The Behind the Candelabra star will play scientist Hank Pym in the new superhero film which stars Paul Rudd as Scott Lang, Marvel has revealed.

In the comics, Pym was the original Ant-Man before the mantle was passed on to Lang.

Kevin Feige, Marvel Studios President, said of the news: "With Hank Pym's rich history in the Marvel Universe, we knew we needed an actor capable of bringing the weight and stature to the role that the character deserves.

"We felt incredibly relieved when Michael Douglas agreed to step into the part with the charm and fortitude he brings to every character he inhabits, and couldn't be more excited to see what he will do to bring Hank Pym to life."

Rudd was announced to have landed the role of Ant-Man last month, having been an early favourite to take on the part.

The forthcoming movie, which will be directed by Edgar Wright, is scheduled to be released on July 31, 2015.
