A new TV commercial has been released for the forthcoming Marvel superhero movie “Ant-Man.” It shows star Paul Rudd’s character, Scott Lang, getting released from prison after a three-year term. Hank Pym (played by Michael Douglas) can be seen telling Lang that “his chance to redemption is becoming Ant-Man.”

Lang is then shown turning into Ant-Man. Pym tells him that as Ant-Man he “can go anywhere, can see everything, can become the hero and protect the world." The spot ends with Lang saying, “It should not be too difficult.”

“Ant-Man” concerns a petty thief, Lang, who must help his mentor Pym in safeguarding the mysterious Ant-Man technology -- which helps him decrease in size and increase in strength. He must plot a heist to save Earth from a lurking danger. Peyton Reed has directed from a story by Edgar Wright and Joe Cornish, based on the comic book “Ant-Man,” by Stan Lee, Larry Lieber and Jack Kirby.

Rudd also co-wrote the screenplay, with Edgar Wright, Jo Cornish and Adam McKay. "I’ve actually found myself in these kinds of situations before -- maybe not quite on this level, but not far off -- where all of a sudden you’re writing scenes and taking on writing responsibilities. And that’s OK. But it’s a little strange writing something that’s really, truly out of my comfort zone,” Rudd told Entertainment Weekly.

Wright, who later stepped down from the film due to creative differences, cast Rudd in “Ant-Man.” “It all happened pretty quickly. Edgar called me, and then it was just out in all the trades. It was a bit of a whirlwind, to say the least,” Rudd said.

“Ant-Man” opens July 17 in 3D and Imax 3D. Other cast members include Evangeline Lilly, Corey Stoll, Bobby Cannavale, Michael Peña, Tip "T.I." Harris, Wood Harris, Judy Greer and David Dastmalchian. Christophe Back has supplied the music and Russell Carpenter has done the cinematography.
