Tony Leung practices kung fu on this undated file photo.

Hong Kong actor Tony Leung broke his arm on Monday while practicing martial arts for his next film, "Grand Master".

Leung, who was cast as Ip Man in director Wong Kar-war's new project was practising a fight scene with several other kung fu practitioners. Both Leung and the others used their full strength to create an actual fight. However, Leung missed a kick from an opponent and his left arm was hit, according to a report on the web portal on.cc.

The "Lust, Caution" star is expected to recover in five to six weeks - the report quotes a doctor as saying.

"Grand Master", or "Yi Dai Zong Shi', is a biopic based on the life of Ip Man, who was internationally known as the master of the late kung fu star Bruce Lee. Filming is set to start in August or September, according to earlier reports. It is not yet known if the schedule will be delayed by the actor's injury.

At the end of last year, "Ip Man', a film with a similar subject featuring Donnie Yen as Ip Man, won both critical and box office success in China.
