After some tiny teases, Marvel released the first full trailer for “Ant-Man” during “Marvel’s Agent Carter.” Starring Paul Rudd, Michael Douglas, Corey Stoll, Michael Pena and Evangeline Lilly, the forthcoming — and frequently embattled — superhero movie is about a small-time crook who, through some interesting twists of fate, is given technology that makes him really small. (That effect looks kind of cool by the way!) “One question,” asks Rudd’s Scott Lang to Michael Douglas’ Hank Pym. “Is it too late to change the name?” Probably, yes. Directed by Peyton Reed, “Ant-Man” is out on July 17.
