Joseph Gordon Levitt and Paul Rudd are said to be the two main contenders for an adaptation of Marvel’s Ant-man.

A source told Variety that the two men are to meet with Marvel executives and director Edgar Wright one more time before a final decision will be made on who will land the title role. They added that there is still a chance of another actor entering the mix.

In the Marvel comics, Ant-man is the alter ego of a scientist who invented a substance that allowed him to change his size.

Ant-man is due for release in 2015.
