Panzehir (2014)

aka: Antidote

Kadir Korkut (Emin Boztepe), nicknamed the “Demon,” wants to retire from the Istanbul criminal underworld and settle down with a blind pianist. But his boss and foster father, Kara Cemal (Cüneyt Arkin), poisons Kadir and forces him to perform two final hits on the two largest rival families in order to receive the antidote. Also stars Çagdas Agun and Tolga Akdogan. (In Turkish language, with English subtitles).

In 1986 Emin Boztepe challenged William Cheung at a seminar in Germany after Cheung formally stated that he could easily beat any fighter from Emin's former organization. Boztepe allegedly gave Cheung no warning before switching from practice to real fight. At the end of the fight even though Emin landed on top, Cheung had no marks on his face and did a photo shoot after the fight.
