The UK premiere of a Chinese-made documentary, "The Sinking of the Lisbon Maru," took place in London on Monday night. The film is about a tragedy during World War II, when some 800 British prisoners of war died at sea after the Japanese ship they were on was torpedoed. Several hundred others were rescued after Chinese fishermen risked their lives to pull them from the shark-infested East China Sea. CGTN's Michael Voss attended the premiere at the Regent Street Cinema.
