Memorial Day options: "Battleship" is a goofball sci-fi movie, but there are half a dozen roles in the movie for actual veterans -- of WWII and Iraq. Also this week: George Lucas' "Red Tails," his passion project about the Tuskegee Airmen. The movie focuses on the African-American fighter squadron (Terrence Howard, Cuba Gooding Jr.) that saw action in Europe in WWII. The movie has a flag-waving, ultra-patriotic tone that seems out of step with contemporary war-movie attitudes, but Lucas has said he wanted it to be the movie that SHOULD have been made for the airmen in the 1940s or early 50s, before Hollywood was ready to make it (they were barely ready in 2011). "Act of Valor," the action movie featuring real Navy SEALs in action based on actual missions, arrives on DVD June 5.
