2.0 is a 2018 Indian Tamil-language science-fantasy action film directed by 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. 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. 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 2.0 became the highest-grossing Indian film of 2018 and highest-grossing Tamil film of all time.. It also ranks among highest-grossing Indian films .

Eight years after the events of the first film, Dr Vaseegaran creates an android humanoid assistant named Nila, which he introduces to a group of college students while reminiscing about Chitti, his previous creation, which he had to dismantle after the robot had gone on a murderous rampage. Shortly afterwards, all the cell phones in the city fly into the sky, causing a public panic. A council of politicians and scientists discusses the phenomenon, with Vaseegaran suggesting reactivating Chitti. However, a council member named Dhinendra Bohra opposes the idea, as Chitti killed his father.

The cell phones swarm and kill several people, forcing the Home Minister to allow Vaseegaran to reactivate Chitti. An upgraded Chitti fights the giant bird-shaped swarm as it wreaks havoc in the city. Chitti runs out of power and recharges on a space station. The swarm tries to follow, but the station's antennas repel it.

Chitti and Vaseegaran confirm that a concentrated mass of negatively charged ions with electromagnetic properties powers the phones, which the positively charged ions streaming from the antennas repelled. Vaseegaran builds a photon synthesizer and uses it to neutralise the charge of the bird with Chitti's help. The defeated phones take the form of a deceased ornithologist, Pakshi Rajan. Chitti converses with Pakshi and learns about Pakshi's past.

Pakshi was a passionate ornithologist who had a bird sanctuary at his house. He protested the excessive use of mobile phones, alleging that high-frequency electromagnetic radiation from cell sites threatens avian life. However, he lost all attempts to warn the public about the harmful effects of cell phone radiation on birds, which led to many of his birds dying. He reported it to some people in the cell phone industry, but they disregarded the matter intentionally. Deeply frustrated, Pakshi hangsmed himself to death from a cell tower. His aura, combined with the auras of the deceased birds, turned into a vengeful aura made of negative energy that can control cell phones with electromagnetic radiation.

Sympathizing with Pakshi, Chitti tries to convince him not to harm the public, but Pakshi refuses, wanting to avenge the deaths of his birds. Chitti captures and contains Pakshi, earning praise from the country. The government commissions Vaseegaran to produce more robots to support the army. Angered at Chitti's victory, Dhinendra sneaks into the AIRD institute and releases Pakshi's aura from the containment circuit, which possesses Vaseegaran and causes chaos again. Chitti confronts a possessed Vaseegaran but refuses to harm him, allowing Pakshi to disassemble Chitti and fly away, converting himself into an avian humanoid. On Vaseegaran's orders, Nila retrieves the red chip that had caused Chitti to go on a rampage eight years ago. Nila restores Chitti and embeds the red chip in it after reprogramming it to make Chitti target only Pakshi and not the public. Pakshi traps thousands of people in a football stadium using cell phones and kills Dhinendra by focusing radiation from cell towers. Chitti, with an army of robots, arrives and fights Pakshi but eventually loses power. Pakshi creates bird drones to attack, but before he can kill the people in the stadium, Chitti's small robot, Kutti "3.0", intervenes. Hundreds of such micro-bots latch onto all the cell phone structures (including Pakshi's wings made of cell phones) and destroy them by exploding themselves.
