The pair spent days shooting a car chase in Casablanca, Morocco, and Cruise made Pegg sweat in the already-sweltering temperatures by secretly turning on the vehicle's heater.

The 45 year old eventually caught Cruise in the act and knew he had to find a way to get his revenge.

"The end game was marvelous. He went to the bathroom and I called over one of the camera guys and I was like, 'Give me a really small sliver of black tape,' and I put the tape over his light on his seat (warmer) so he couldn't see that it was on and then I put it on full blast. He came and sat down, cooked, and he kept looking at the light like, 'Why is it so hot?' and then he realised that he gave me that (prank)."
