New 'Ant-Man' trailer shows Paul Rudd face off against Corey Stoll

Scott Lang’s days of breaking into places and stealing stuff are over, because as Ant-Man, he’s going to… well, he’s still going to break into a place and steal some stuff. He’ll just be really tiny this time.

Marvel has unveiled a new trailer for its second film this year, Ant-Man, offering a better look at the film’s large and small-scale scope, story, and main players.

Most importantly, the trailer actually sets up what the stakes of the film are. Corey Stoll’s Darren Cross (aka Yellowjacket) delivers the first lines of the trailer, hinting at the design of a certain suit that will give great power to the smallest of fighters. Paul Rudd’s Lang also learns about the abilities his suit affords him and shows them off in a few action sequences, including one that looks quite a bit like the first test footage ever shown of the film.

The trailer includes a surprising amount of footage of Lang’s escapades as an ant-sized man as he learns to work alongside his newfound army of insects. Michael Douglas as Hank Pym and Evangeline Lilly appear sporadically throughout the trailer, which also indicates Ant-Man may be the first—and probably only—superhero movie to ever culminate in a battle taking place atop a child’s train set.

But no matter where Lang is fighting, he and even his enemies have some trouble getting used to a name like “Ant-Man.”
