Michael Douglas is set to join Paul Rudd in the cast of Edgar Wright's Ant-Man, Marvel Studios have announced.
The 69-year-old Oscar winner, who won a Golden Globe award for his portrayal of flamboyant entertainer Liberace in Behind The Candelabra, will play scientist Henry 'Hank' Pym in the upcoming superhero movie.
The actor revealed he has wanted a role in a Marvel film for a while, and said he wants to make a film for his 13-year-old son Dylan.
He told Reuters: "I've been dying to do a Marvel picture for so long. The script is really fun, the director is really good. Dylan will love it. He'll have a picture he can see. "
Marvel Studios President Kevin Feige said he can't wait to see what Michael will bring to the part.
"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," he said.
"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."
Hank, who made his debut in the comic books in 1962, invented a substance that would allow him to shrink down to tiny proportions, while still packing a full-bodied punch.
Paul will take the title role of Scott Lang - a thief who becomes superhero Ant-Man after he steals Hank's shrinking suit. He becomes an affiliate of The Fantastic Four and a member of the Avengers in the comics.
Ant-Man, which has a script written by Edgar and Joe Cornish, is set for release in July 31, 2015.
