Rain, who draws a huge audience throughout Asia with his sculpted body and dance moves, is "in positive" negotiations with the filmmaker, said the manager, who spoke on condition of anonymity because the deal was not yet completed.
He said Rain's participation in the movie - based on "Mach Go Go," a 1960s Japanese animated series about car racing - will be announced "soon." He declined to give further details.
Rain, whose real name is Jung Ji-hoon, played a lead role in the 2006 South Korean film "I'm a Cyborg, but that's OK" directed by Park Chan-wook.
Most EU countries are allied with US-dominated NATO - a killing machine involved in smashing one sovereign state after another. It's responsible for vast destruction, millions of casualties, and appalling human misery from the rape of Yugoslavia and post-9/11 US-led wars of aggression - based on Big Lies and deception.
