The first look at the Marvels Ant Man. First impressions. Cooooooooollll. But then again I am in with everything Marvel.

Thief Scott Lang must aid his mentor Dr. Hank Pym in safeguarding the mystery of the Ant-Man technology – which allows its user to decrease in size but increase in strength – from various new threats, and plot a heist that will save the Earth.

Paul Rudd as Scott Lang / Ant-Man:
A petty criminal, who acquires an invented substance that allows him to shrink in scale but increase in strength. Regarding Rudd’s casting, producer Kevin Feige said, “Look at that origin of the petty crook who comes into contact with a suit and does his best to make good, and then look at someone like Paul Rudd, who can do slightly unsavory things like break into people’s houses and still be charming and who you root for and whose redemption you will find satisfaction in.”
Evangeline Lilly as Hope Van Dyne:
The daughter of Hank Pym and Janet Van Dyne. Describing her character, Lilly said, “I was raised by two superheroes. So, I’m a pretty screwed up human being. I am also fairly capable, strong, and kick-ass, which is wonderful to play, but the most fun to play was just how messed up she was from being raised by two superheroes. And the clear message sent by my name is that I’m not a big fan of my father and so I took my mother’s name.”[10] Originally cast by Wright, Lilly was reluctant to take the role after he left the project until she read the revised script and got a chance to meet with Reed.
Corey Stoll as Darren Cross / Yellowjacket:
A former protégé of Pym, who takes over Pym’s company and acquires the Ant-Man technology to create the Yellowjacket suit. Describing the suit, Stoll said, “Darren Cross… has a suit that is sort of the next generation of Ant-Man’s suit. It can do everything that Ant-Man can do, but more. It’s more badass, more militaristic, sleeker… sort of like if Apple had designed a battle suit.” As for his character, Stoll said, “He is not a villain in the vein of Thanos or Loki, who are villains that know it. [Cross] is a guy who is not that dissimilar from Michael Douglas’ character, Hank Pym. A brilliant scientist, who is not ethically pure. I think a great thing about the whole movie is that everybody in this movie is in those shades of gray a little bit.”
Bobby Cannavale as Paxton: A friend of Lang.
Michael Peña as Luis.
Judy Greer as Maggie: Lang’s estranged ex-wife.
Tip “T.I.” Harris as Dave.
David Dastmalchian as Kurt.
Wood Harris as Gale.
Jordi Mollà as Castillo.
Michael Douglas as Dr. Hank Pym / Ant-Man:
An entomologist and physicist who invents the Ant-Man technology in 1963 and mentors Lang to take over as Ant-Man. Douglas compared his decision to join a superhero film to his role in Behind the Candelabra saying, “Sometimes—like [when] they didn’t see you for Liberace—you’ve got to shake them up a little bit and have some fun.” Douglas indicated that he will not be wearing the Ant-Man suit, saying, “My costume will be hung up and Paul will be wearing it in good form.”
Additionally, John Slattery reprises his role as Howard Stark from Iron Man 2. Abby Ryder Fortson, Gregg Turkington, and Martin Donovan have been cast in undisclosed roles.
