The film was shot at various locations , including Chennai ( India ) , Kuala Lumpur ( Malaysia ) , Bangkok ( Thailand ) and Singapore . The crew , including director Raja , Jayam Ravi , manager Senthil , cinematographer B. Rajasekar and art director Milan had been looking for locations in Malaysia in August 2009 , after which the film shooting began . At first , shooting was held in Chennai for nearly 20 days , following which the crew flew to Malaysia , where a major portion of the film was to be shot , where the original film was shot as well . By mid-November , the crew had completed a 30-day schedule in Malaysia . The shoot in Malaysia involved an action sequence , filmed by three cameras simultaneously , which was shot on busy roads with special permissions from the local police authorities and a song sequence featuring Ravi and Tamannaah . Shooting was held also at the famous Petronas Twin Towers and on the Singapore-Malaysian railway line . During the 30-day filming , the September 2009 Sumatra earthquakes occurred , which the team luckily survived . In late January 2010 , a special song ( " Solpechu Ketkadha Sundari " ) , widely publicized as the " 360 degree song " was shot . It was filmed using a Nero motion control camera that revolves on a 360 degree angle set , which was handled by an Australian specialist Scott and would later look like a single shot . This song , choreographed by Shobi , which would feature 15 Jayam Ravis and 5 Tamannaahs , was completed in around 45 hours , on which alone nearly Rs. 75 lakhs was said to be spent
