Ant-Man offered a lighter take on the Marvel Cinematic Universe when it arrived in 2015. Revolving around an ex-con (Paul Rudd) who gets technology that lets him shrink (or become a giant) at will, it ended with a tense climactic fight inside the cavernous lair of a small child?s bedroom. And it looks like the shrinking and expanding hijinks are just getting started in this first trailer for Ant-Man And The Wasp.
