After going intergalactic with “Guardians of the Galaxy,” and hanging an entire city from the sky in “Avengers: Age of Ultron,” Marvel is reversing its scale but still packing the punches with an insect-sized superhero. “Ant-Man,” out in movie theaters on Friday, sees a new addition to Disney-owned Marvel’s expanding universe as Paul Rudd steps into the Ant-Man suit, which allows the wearer to shrink and gives him super strength. The film follows the origins of Ant-Man, otherwise known as Scott Lang.
