2.0 is a 2018 Indian Tamil-language 3D science-fantasy action film directed by S. Shankar who co-wrote the film with B. Jeyamohan and Madhan Karky. Produced by Subaskaran under the banner of Lyca Productions. As the second instalment in the Enthiran film series, 2.0 is a standalone sequel to Enthiran (2010), featuring Rajinikanth in a triple role as Vaseegaran, Chitti the Robot and Kutti, alongside Akshay Kumar as Pakshi Rajan (in his Tamil debut) and Amy Jackson as Nila, Sudhanshu Pandey, Adil Hussain, Kalabhavan Shajohn, and K. Ganesh appear in supporting roles. The soundtrack is composed by A. R. Rahman, with lyrics written by Madhan Karky and Na. Muthukumar. The film follows the conflict between Chitti, the once dismantled humanoid robot, and Pakshi Rajan, a vengeful avian human, who seeks vengeance upon cell phone users to prevent the death of birds due to cellphone radiation.

Production began in 2015, with principal photography conducted at AVM Studios later that year. The first schedule was filmed at EVP World. Scenes were primarily shot in India, particularly in Chennai's Madras Boat Club and Delhi's Jawaharlal Nehru Stadium. Filming was completed by August 2017. The film is the first in Indian cinema to be natively shot in 3D, which was done by cinematographer Nirav Shah. The film was primarily shot in Tamil while Akshay Kumar and some actors' dialogues were shot in Hindi. Legacy Effects made their return to construct prosthetic makeup and animatronics, with visual effects supervised by V. Srinivas Mohan. Editing was handled by Anthony and production design was conducted by T. Muthuraj.

2.0 was released worldwide in both 3D and conventional format on 30 November 2018, along with its Hindi and Telugu dubbed versions. The film received mixed reviews, with praise towards the direction, performances of Rajinikanth and Akshay Kumar, visual effects, action sequences, soundtrack and social message, although the screenplay received criticism. The film faced scientific criticism too, with Audubon society censuring this film for propagating this misinformation regarding the impact of mobile phone towers on birds, in an article debunking this misinformation. Indian scientists and wildlife experts, too, called out the conspiracy theory, which forms the core idea of the film. It became the highest-grossing Indian film of 2018 and highest-grossing Tamil film of all time.
