I don't know if the actual universe is expanding but the Marvel Cinema Universe is growing unabated. The latest Marvel star is Paul Rudd as Ant-Man, cat burglar turned super hero Scott Lang. Rudd is a beguilingly self-deprecating comic actor, whose character is enlisted by aging genius inventor Hank Pym (Michael Douglas) and, reluctantly, his daughter (Evangeline Lilly) to don a miniaturizing suit and lead an army of ants against former student and present nemesis Darren Cross (Corey Stoll), who wants to militarize Pym's research and score a big payday. Veteran TV director Peyton Reed crafted this film with an eye toward the natural incongruities -- hardscrabble con artist and thief working with former S.H.I.E.L.D. operative -- to impressively comedic effect. Speaking of effects, the opening set piece that introduces our hero to the wonders and dangers of an insect-size existence are, er, Marvelous, which is to say this often uproarious movie is best enjoyed in 3D.
