Tom Cruise Holds His Breath Underwater For Six Minutes [VIDEO]

Tom Cruise has been involved in some pretty crazy "Impossible Missions," but this one left my jaw on the floor!

Stunt work for the new "Mission Impossible" movie involves underwater scenes so it's only natural the Mr. Cruise does the stunts himself, right? But in order for him to do this, he had to prove that he could hold his breath...for SIX minutes!

And just so know, the record for breath-holding is twenty-two minutes! Who does that???
