Hugh Jackman was left drenched in water after losing a card game against Jimmy Fallon.

The Real Steel star faced off against the late night talk show host in a game of War, with the loser of each round being drenched in a glass of water.

The ultimate winner was allowed to use a water cannon against the loser.

"We are going to have a water war. Now, it's just like the card game War, but with water. So, if you lose a hand you get splashed in the face. We each have five cups of water. The first one to use all of his cups on the other guy wins and gets to water canon the loser," Fallon told Jackman.

"Lots of ways to get wet, but only one way to win."

Jackman took an early lead, but Fallon won out in the end.
