Just when we thought we'd had enough of the ice bucket challenges -- Tom Cruise had to go and do this!

On Tuesday, the superstar accepted the ALS Ice Bucket Challenge given to him by Pan stars Hugh Jackman, Rooney Mara and Garrett Hedlund, while on the set of his new film, Mission:Impossible 5 .

Cruise and his M:I 5 director Chris McQuarrie really upped their bucket game when they a seemingly endless amount of buckets dumped on their heads.

Cruise and McQuarrie challenged Paramount execs (aka their bosses) Adam Goodman and Brad Grey, as well as Skydance's David Ellison.

Celebs and non celebs all over the world have been getting in on the Ice Bucket Challenge over the past week -- each video seems to get more elaborate. Ben Affleck knocked wife Jennifer Aniston into the pool during his video. David Beckham traded in a bucket for a barrel of ice water.

The icy endeavor is part of a worldwide viral campaign to raise money to fund a cure for amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease or Motor Neurone Disease.

Vin Diesel also decided to show that he was tuff stuff for his ALS challenge -- when he dumped a bucket of pure ice on his head while in his pickup truck. Looks like someone's proud to be an American! After he iced himself, the Fast & Furious actor nominated Michelle Obama, Angelina Jolie and ... Vladimir Putin -- that's an interesting trio!
