Quick-shrinking superhero Ant-Man made his Marvel Comics debut in 1962, and this expensive summer blockbuster marks his first cinema appearance. Paul Rudd stars as Scott Lang, a burglar persuaded by scientific genius Dr.Hank Pym (Michael Douglas) to wear a special suit that will make him insect-sized so he can break into Pym’s former company and prevent his size-changing technology being sold to warmongers. Director Peyton Reed (Bring It On) mixes nifty visuals with moments of light relief supplied by Lang’s wisecracking sidekick Luis (Fury‘s Michael Peña) to make a consistently entertaining and likeable popcorn flick. But thanks to an obvious backstory involving Lang’s estranged daughter and a predictable romantic subplot linking him to Pym’s daughter (Lost‘s Evangeline Lilly), Ant-Man often feels formulaic too.
