DVD releases: Hero meets five nemeses in ‘Iron Man 2’

“Iron Man 2”: Shaggily enjoyable follow-up to the 2008 blockbuster, starring the delightful, delirious Robert Downey Jr. as the self-made superhero who encounters five (count ’em! five) new nemeses. With Gwyneth Paltrow, Scarlett Johansson, Don Cheadle and Mickey Rourke. (2:05; PG-13 for violence and language) • • •

“Get Him to the Greek”: Think of this “Forgetting Sarah Marshall” spinoff, reuniting supporting actors Russell Brand and Jonah Hill as a rock star and fanboy, as a very naughty version of “Almost Famous.” This time, the fanboy does not write the rock star’s legend, but helps restore him to his former glory. With P. Diddy, Rose Byrne and Elisabeth Moss. (1:49; R for sexual content, drug use and language) • • •

“Babies”: Guaranteed to elicit tsunamis of “oohs” and “awwws,” this narration-less documentary focuses on four newborns from different cultures and countries: Namibia, Mongolia, the U.S. and Japan. The cute factor is through the roof in this transcontinental celebration of teeny, tottering humanity. (1:19; PG for cultural and maternal nudity) • • •

“Coco Chanel & Igor Stravinsky”: A luxe-laden account of the storm-tossed romance between the French fashion icon and the Russian musical genius, set in 1920s France, and full of raging emotions and dazzling couture. (2:00; R for sex, nudity, adult themes) • • •

Also available: “Frozen,” “The Killer Inside Me”
