DVD Tuesday: ‘Cloverfield’, ‘Charlie Wilson’s War’

Reality and fiction have a twisted sort of relationship that is often hard to untangle, especially in any movie that attempts to say it is “based on a true story.” Arriving this week on DVD are three films aspiring to reality, in one form or another, but with varied results. New arrivals include the monster movie Cloverfield, the political drama Charlie Wilson’s War, and the sports tale, Resurrecting the Champ.
