( CNN ) The thing about the old card game of War is that anything can happen . In Chris Hemsworth 's case , he got drenched with water . The `` Blackhat '' actor , appearing on `` The Tonight Show Starring Jimmy Fallon , '' took on the host in War , in which the competitors turn over playing cards , with the higher card designated the winner . In the Hemsworth-Fallon battle , there was an extra twist : After each card was turned , the winner got to throw a glass of water at the loser . At the conclusion , the person with the most wins got to soak the other with a water cannon . Hemsworth held his own in the early going , but things did n't turn out well for the Australian actor . Perhaps things go better in `` Blackhat , '' which opens Friday .
Chris Hemsworth and Jimmy Fallon play Water War . The movie is based on the book by John Green about a group of friends who go to an island off the coast of Maine for spring break.
