The only two of these parodies I recognize on sight is post #157846, of Kiki's Delivery Service, and Futo as Charlton Heston in The Ten Commandments. Some help adding tags would be quite welcome.
Most of these may or may not represent parodies of actual movies. The theme is mocking the various style of Hollywood movie posters. The main page describing the phenomenon can be found here. (Warning, copious amounts of Japanese). I've include a translation of the various items below.
Was about to call out on Mr. & Mrs. Smith, but then I remembered they did the exact opposite. Still, those links are hilarious and somewhat saddening, were I to allow myself to care.
