Tom Cruise had to eat "three dinners" every night while filming tough stunts for 'Mission: Impossible -Fallout'.The 55-year-old actor is already an accomplished pilot but spent 18 months learning how to fly helicopters for a sequence in the next instalment of the action franchise, and the adrenaline of shooting the scenes left him with some "fascinating" side-effects.He explained to Total Film magazine: "The adrenaline was going so hard that I would finish at the end of the day, and I'd have to go home and eat three meals."I'd have to have three dinners. My body couldn't get enough food and my legs ached from adrenal fatigue. It was fascinating."Tom is renowned for doing his own stunts but left the crew terrified when he was undeterred by the failure of camera rigs which had been designed to safely film him on a motorcycle, and simply took off on the vehicle anyway.
