With Avengers: Age of Ultron almost in theaters, Marvel is starting to turn it's attentions toward their second summer release for this year, Ant-Man. After a teaser and a full-length trailer that were well-received by the fans, the first clip has arrived courtesy of star Paul Rudd himself, who showed it off on Late Show with David Letterman. Here, we get a sense of the film's humor, its tone and how some of the action plays out. We're also introduced to one of Scott Lang's crime buddies Luis, played by the great Michael Pena.

Armed with the astonishing ability to shrink in scale but increase in strength, con-man Scott Lang must embrace his inner-hero and help his mentor, Dr. Hank Pym, protect the secret behind his spectacular Ant-Man suit from a new generation of towering threats. Against seemingly insurmountable obstacles, Pym and Lang must plan and pull off a heist that will save the world. In this first clip, we watch as Lang shows off some of his skills as a master criminal.

Scott, Luis and Kurt (David Dastmalchian) have broken into a large impenetrable safe. But what they find on the other side is not what they expect. Here, Lang, who is in charge of the operation, comes in contact with the Ant-Man suit for the first time. And it will alter his life in unexpected and surprising ways. Directed by Peyton Reed, Ant-Man also stars Michael Douglas, Evangeline Lilly, Judy Greer, Corey Stoll, John Slattery and, in a break out role that has everyone talking, Neil Hamburger!
