My son and I were debating the merits of getting a Roku box. When I mentioned that they provide many of the movies on modified full screen format he replied that he doesn’t care all that much. (I promptly cancelled his allowance and confiscated his Christmas loot. He then reminded me that he watches black & white movies with me, so I reinstated his Christmas gift. Had already spent the other.) Anyway, he then asked what mainstream movies make use of the outside of the frame and I didn’t have an answer. Can you guys help, what movies have necessary or even interesting information in the portion of the frame that is removed with modified aspect ratio?
