ALAN Alda and Wayne Rogers love movies, but they have trouble remembering titles. As the “M*A*S*H” stars discussed indie films on the Fox Business Network, Alda noted, “One year was ‘My Big Fat Green Wedding.’ ” When Rogers corrected, ” ‘My Big Fat Greek Wedding,’ ” Alda shot back, “I was getting too environmental.” Then Rogers said, “There was another one – ‘Little Mary Sunshine.’ ” Alda, in town promoting his new movie, “Diminished Capacity,” pointed out it’s “Little Miss Sunshine.”
