Petta is an upcoming Indian Tamil-language action film written and directed by Karthik Subbaraj and produced by Kalanithi Maran. The film stars Rajinikanth with ensemble cast including Vijay Sethupathi, Simran, Trisha, M. Sasikumar, Nawazuddin Siddiqui, Bobby Simha, J. Mahendran and Guru Somasundaram.
Vijay Sethupathi was signed on to play a character in April 2018, and accordingly reworked his dates to fit the film into his busy schedule. The actor signed the film after a month of media speculation that he would portray a villainous role, and revealed that he signed the film as he had blind trust in Subbaraj, and initially did not request to listen to the script. Subbaraj had also been keen to sign Fahadh Faasil for a role in the film, but the actor's filming commitments for Varathan (2018), meant that he could not allot dates. Hindi film actor Nawazuddin Siddiqui joined the cast in July 2018, while two other regular collaborators of Subbaraj, actors Bobby Simha and Sananth, were also signed to play pivotal roles in the film. Other members of the cast included supporting actors Guru Somasundaram, Ramdoss, Shabeer Kallarakkal, Deepak Paramesh, Aaditya Shivpink, and Manikandan R. Achari.
For leading female roles, the team held discussions throughout March 2018 with actresses Trisha, Deepika Padukone and Anjali but neither were signed immediately. In July 2018, the producers announced that Simran had joined the cast to play as pair of Rajinikanth. Trisha was eventually added to the cast in August 2018, while Malavika Mohanan was also signed to appear alongside Rajinikanth. Megha Akash was cast as Kerrthi Vasan pair, and joined the shoot before the release of any of her initial Tamil films, Boomerang, Enai Noki Paayum Thota and Oru Pakka Kathai. In October, M. Sasikumar and J. Mahendran joined the cast.
Principal photography began in June 2018. The first schedule of the shoot began on 7 June at Eastern Forest Rangers College at St. Mary’s Hill, Kurseong in Darjeeling, with the initial portions lasting nine days. The team then shot in other location across Darjeeling and the hill towns for a further month, in locations including St. Paul’s and Mount Hermon School. To finish the first schedule, the team returned to Kurseong for six days. An audition to cast 150 local actors was also held in Charbagh, Lucknow during the first schedule. During the making of the schedule, Rajinikanth met with politician Gautam Deb, who helped the makers have a hassle free shoot in exchange for the promotion of tourism in the area. Principal photography wrapped in October 2018, fifteen days ahead of schedule.
