Watch Will Ferrell perfectly lip sync ’Let It Go’ on Jimmy Fallon’s Superbowl episode

This is the Superbowl with a difference; the ’Lip Sync’ Superbowl on Tonight with Jimmy Fallon.

This year it was Will Ferrell taking on Kevin Hart and the Anchorman star pulled out all the stops to win including a wonderfully demonstrative performance of 'Let if Go' from Disney's Frozen.

Here it is, hilarious and disturbing in equal measure.
