copyright 2009, The Washington Post FOOD, INC. PG, 2008, $26.98; Blu-ray, $34.98 The basics: This documentary from Robert Kenner lifts the curtain on the workings of the modern food system, highlighting how our food supply is controlled by a handful of corporations. The lowdown: You should consider eating dinner BEFORE watching this absorbing film, but you should watch it. Post critic Ann Hornaday says that Kenner, through hidden-camera footage and interviews, 'goes beyond sensationalism to connect a number of seemingly unrelated dots. ... Americans' dining habits aren't merely a matter of healthy choices, but political ones, too.' Kenner's film might even make you think twice about that spoonful of organic yogurt. The extras: Deleted scenes and celebrity public service announcements, among others. LEMON TREE Unrated, 2008, $19.98 The basics: The odds are stacked against a Palestinian widow whose family's West Bank lemon grove is declared a security risk after the Israeli defense minister and his wife move in next door. The lowdown: This evocative drama from writer-director Eran Riklis ('The Syrian Bride') plays like a fable, but it's based on a true story and highlights the real-life tensions and unease of everyday life on the West Bank. As Post critic Philip Kennicott said, 'The irony of the film is that what it achieves adds, in the end, to the sense that nothing can unravel this mess.' The extras: Film trailer. SAY ANYTHING: 20th ANNIVERSARY EDITION PG-13, 1989, $19.98; Blu-ray, $34.99 The basics: The rom-com that launched the raising of a thousand boomboxes marks its 20th anniversary with a new DVD and Blu-ray release. The lowdown: The story of how kickboxer Lloyd Dobler (John Cusack) loves, then loses, the class valedictorian (Ione Skye) remains one of the most beloved high school movies of all time. It dared to be great and still is. Adding to its greatness? A couple of new extras, including the featurette 'An Iconic Film Revisited: `Say Anything ... ' 20 Years Later' in which Cusack notes that he really didn't want to hold up that boombox during the movie's iconic scene. But director Cameron Crowe insisted. 'Trust me,' he said. Thankfully, Cusack did. The extras: Commentary by Crowe, Cusack and Skye (also on earlier releases) and deleted scenes.
