“The Hope and the Change” is a new documentary film about voters who cast their ballots for Barack Obama in 2008, but who are disenchanted with the president and won’t for him again. “Won’t Back Down,” which opens Friday and stars Viola Davis (left) and Maggie Gyllenhaal, is seen by some as an attack on teachers unions and has been embraced by proponents of school choice. “Act of Valor,” a pro-military film starring real Navy SEALs and seen as a counterpoint to a rash of anti-war movies over the past few years, cost about $12 million to produce but grossed more than $80 million for its makers.¿
