So, to tell you about the movie "Before I Go To Sleep". It has outstanding performances by both Colin Firth and Nicole Kidman. Following the storyline of the book, Kidman does "wake up in a new world" every morning, not even recognizing her "husband" Colin Firth. Keeping to that storyline becomes a teeny bit repetitious even confusing when you are not quite sure if the scene is the one you saw before, or a new morning. After they get you into the groove of that, the story progresses, a bit slowly, as she gains tiny bits of memory. The doctor who is working with her, surreptitiously, is trying to increase these bits until she can recall how she became injured in the first place. As the movie progresses, I found my heartbeat speeding up! Not scared out of my seat, but reacting to the "thriller" segments. It has been quite sometime since I originally read the book, so I was unsure if they maintained the ending properly. Loose ends were tied up, so I had no quarrel with that. Frankly I didn't remember any of the storyline, except the bare bones so to speak, so I was awakening in a new world too!
