Tom Cruise and Jimmy Fallon get soaked during water war
"This is just like the card game War but with water," Fallon explains.
The loser of each hand got a glass -- or in a couple of cases, a pitcher -- of water thrown in his face or over his head. Both Fallon and Cruise ended up soaked in the end, but Cruise rallied at the end of the best-of-nine series and got the ultimate prize -- shooting his opponent with a plastic water cannon.
The 50-year-old actor also managed to get in some promotion for his new movie, out Friday, and told some tales from the filming -- including how he got his most painful injury on the set.
"The worst injury I had from 'Jack Reacher' was ... I hurt my foot," Cruise says. "There's a scene where I'm kicking a guy in the b***s, the testicles. It was a human being -- no testicles were injured in the making of the film!"
He continues, "We had to do the take over and over again, and the first 10 times it was like 'Yeah!' ... after about 50 times in, my foot was swelling ... I kept having to loosen my shoe."
"Your foot! Imagine the poor guy's testicles!" Fallon jokes. "Maybe Jack Reacher should wear Ugg boots."
"I was limping for days," Cruise says, to which Fallon replies, "So was he, I'm assuming."
