The Theory of Everything ' s marketing materials will tell you it is based on Jane Hawking's memoir of her marriage, a book published in the UK as Music to Move the Stars, and then re-issued as Travelling to Infinity. But the screenwriters rearranged the facts to suit certain dramatic conventions. And while that always happens in these based-on-a-true-story films, the scale of the departure in The Theory of Everything is unusually wide. The film becomes almost dishonest–in a way that feels unfair to both parties, and oddly, particularly Jane Hawking herself.
