The 30 Seconds to Mars frontman, who won an Oscar for his appearance in "Dallas Buyers Club", will play an American soldier in the upcoming film set in post-World War II Japan, reports aceshowbiz.com.
First imprisoned, the soldier later gets released with the help of his Yakuza cellmate. Now free, he sets out to earn their respect and repay his debt while navigating the dangerous criminal underworld.
"The Outsider" is scheduled to begin production this fall. Martin Zandvliet, the filmmaker behind "Land of Mine", which was lauded at last year's Toronto International Film Festival, is directing based on a script penned by "Bastille Day" writer Andrew Baldwin.
No release date has been announced yet.
Leto will next be seen on screen as Joker in "Suicide Squad" which is set for an August 5 release in US. (IANS)
