Man of Steel 2013 aka Superman Henry Cavill talked to NBC's Jay Leno to promote his upcoming movie and talk about the complexities of wearing a superhero suit. Meanwhile, the Man of Steel mobile game is coming out in a week's time.

Cavill tells Leno two other guys help get into the suit during filming. "How do you go to the bathroom?" Leno asks. Cavill says he needs about 25 minutes to be able to take nature's call. He has to undress, or unsuit, completely.

"It's not convenient," Cavill chuckles, adding that if he ever does play Superman again, he'd request for some costume adjustment.

"Maybe just a thong," Leno jokes, to which Cavill gamely nods.

"How hard was the American accent for you to do?" Leno asks. Cavill delights many female fans with his natural, perceived-to-be sexy Brit accent. Cavill says he's had enough time for more practice for Man of Steel 2013.

"It's like going to the gym, but for your mouth," he quips.

Viewers of The Tonight Show with Jay Leno were treated to a big action-packed fight between Superman and General Zod. Superman has had enough of Zod at this point, Cavill explains. They battle it out through building and structures, with Superman making sure to cause some real damage to his nemesis. Scroll down for the NBC clip of the interview and Man of Steel 2013 preview.

Meanwhile, those who are waiting for the Man of Steel mobile game will soon be able to play it on their devices.

"Man of Steel game for iPhone, iPad, iPod Touch, Android smartphones and tablets. Available June 14, 2013 on the App Store, Google Play and Amazon Appstore for Android," reads the Man of Steel mobile game trailer description. Play the trailer below.
