Actor Tom Cruise reportedly wears a thong during the action scenes because it is comfortable and flexible.
The 51-year-old, who has done numerous action scenes in movies like "Mission Impossible",
"Days Of Thunder" and "Oblivion", started wearing the undergarment after facing discomfort during heavy-duty scenes.
“There aren't many movies where you don't see Tom rolling around on the ground or doing a back flip off the side of a skyscraper. Over the years it's taken its toll and he had his wardrobe department rustle him up a comfy thong," dailystar.co.uk quoted a source as saying.
“He was embarrassed at first but he sees it as a way of improving his flexibility as he gets older," the source added.
