Action star Donnie Yen has been hitting the gym more often because he will be taking on retired boxer Mike Tyson in the movie Ip Man 3, reported China Press.
The actor, who also starred in the previous Ip Man movies, said he needed to be at his best to "fight" Tyson in one of the scenes.
"I have been looking forward to this and must get myself in the best possible shape for it.
"This fight scene will pitch kungfu against boxing," he said.
He added that since he was not the movie's action choreographer, he could concentrate more on his acting and gym training.
