Bollywood actor Ranbir Kapoor, who is learning martial arts for his upcoming film ‘Dragon’ these days, would reportedly kick-off its shooting in August. According to a report, Ranbir, 33, is currently in Berlin training under Ido Portal, the coach for UFC fighters Conor McGregor and Gunnar Nelson for the next two weeks. A report quoted a source, as saying, “Ranbir’s recent meeting (with Ayan) last week with Portal in Germany was not by chance. Portal specialises in capoeira and Movement Culture, which Ranbir is now learning for his superhero film. Ayan and Ranbir want the action in ‘Dragon’ to be mind-blowing.”The insider added, “Ranbir is extremely kicked about it as it’s a fight and movement technique that no Bollywood actor has done before. He is packing in three months of training into a two-week period as time’s short.” The source further said the ‘Rockstar’ actor would head back to Mumbai to wrap up the last schedule of ‘Jagga Jasoos’ post completing martial arts training and would begin shooting for Ayan Mukerji’s directorial in August.
