Movie adaptations of novels are generally very, very questionable in terms of true-to-the-original accuracy. And novels at least have the advantage of having been written for the kind of entertainment-driven everything-fits-together narrative that movies are compelled to conform to. Real life, with its terribly inconvenient nature for pacing and self-contradicting, does even less well when compacted into 2 hours for a primarily visual medium. If you see a movie adaptation, you can be pretty sure it's inaccurate. The question of accuracy shouldn't be in the detail; it should be in the message that the movie was trying to tell. "Ip Man - A Legend is Born", for instance, conveyed Yip Man's desire to spread Wing Chun better than any other movie biography, whereas "Ip Man" best discussed his philosophy of life and "The Grandmaster" put him into a historical context completely ignored by the other movies. They're all factually wrong, but they're wrong with different emphases and strengths because they're expressing different perspectives on the same life.
