With Reporting by Josh Horowitz

Who knew that Jon Stewart had a serious drama in him? Everyone knows now, thanks to Stewart's directorial debut, "Rosewater," based on the true story of journalist Maziar Bahari's four months of wrongful imprisonment in Iran.

But directing movies isn't Stewart's only hidden talent. Gael García Bernal, who stars in "Rosewater" as Bahari, told MTV News' Josh Horowitz about another of Stewart's secret skills: "He's a great fútbol player."

That's fútbol, not football — as in, "the fútbol you play with your foot," according to Bernal. He said that Stewart's a talented soccer player, as he proved from time to time on the "Rosewater" set, on the rare occasion that the crew enjoyed downtime.

"We didn't have as much time to play as much as we wanted," said Bernal, who noted that "Rosewater" was filmed in Jordan during Ramadan. "In the night, after you break fast, and everyone on the team, we would eat a little bit, and then go for a kick-around. We were shooting close to a very nice fútbol field. As soon as Jon started playing, everyone was like, 'Wow!'"

Bernal credits Stewart's underrated athletic skills to the same things that make Stewart an outstanding television host and film director.

"It has to do with his quick-wittedness and amazing intelligence, and how great his common sense works," he said. "He's good at putting people together and putting people to work on the same journey."

"Rosewater" is in theaters now.
