Music videos
The songs were choreographed by Prabhu Deva, Raju Sundaram, Remo D'Souza, Dinesh and Shobi. The first song "Pudhiya Manidha" was the introduction song for Vaseegaran and Chitti (both played by Rajinikanth) and also appeared in the opening credits. It was choreographed by Prabhu Deva with his Bharata Natyam trained assistant Ajeesh dancing for the robot. "Kadhal Anukkal", again choreographed by Prabhu Deva, is a love song picturised on Vaseegaran and Sana (played by Aishwarya Rai). The song was completely shot from Lençóis Maranhenses National Park in northeastern Brazil. "Irumbile Oru Irudhaiyam", which marked the singing debut of Lady Kash and Krissy in Tamil cinema, was choreographed by Remo D'Souza and was picturised as a club dance number between Chitti and Sana. "Chitti Dance Showcase", a short and mostly instrumental song was choreographed by Shobi and was picturised on Vaseegaran, Chitti and Sana.
"Arima Arima" was set in Ramoji Rao Film City, Hyderabad and was choreographed by Prabhu Deva. It was picturised on Chitti, his robot army and Sana. According to the director S. Shankar, art director Sabu Cyril and cinematographer R. Rathnavelu, picturising this song was the most challenging part of the whole film. The song also features two robotic lions, the creation of which, according to Sabu Cyril, is a professional secret. In an interview, Ratnavelu said, "This film has been a big challenge right from the start till the patchwork. But the most challenging part for me was shooting the climax song, Arima Arima, which will be the USP of the film. The song was shot in a set in Hyderabad in 2008. I had to perceive in 2008 what would be in vogue now. So, that was a real challenge and that has come out really well."
The most notable song in terms of picturisation, "Kilimanjaro", is picturised on Rajinikanth and Aishwarya Rai singing a duet with a host of tribal dancers in the background. The song sequence was filmed at Machu Picchu in Peru, making it the first Indian video to be picturised from the protected heritage site. According to official sources, there were interventions from the Indian government to grant permission for the filming, which was denied to many international projects, such as Quantum of Solace (2008). It was choreographed by Raju Sundaram.
The last song, "Boom Boom Robo Da", shot from Himachal Pradesh and Chennai, was choreographed by Dinesh and picturised on Vaseegaran, Sana and Chitti.
