Things are heating up on set of '50 Shades of Grey' in the sub zero temps in Vancouver, BC, Canada on December 19, 2013. Both Jamie Dornan as 'Christian Grey' and Dakota Johnson as 'Anastasia' are showing their on-screen chemistry after the cameras stop rolling with a little hand touches, ear whispers, sharing hand warmers and continuous laughing in the cool weather.
