Development In May 2019, Producer S. S. Lalit Kumar of 7 Screen Studio and
Viacom18 Studios announced their upcoming project featuring
Vikram, tentatively titled as
Vikram 58. The film is directed by
R. Ajay Gnanamuthu, who previously helmed
Demonte Colony (2015) and
Imaikkaa Nodigal (2018). It was intended to be a
pan-Indian film, set for release in five languages, during the summer in April 2020. By July 2019,
A. R. Rahman was chosen to score the music for the film. Stunt choreographer
Dhilip Subbarayan and cinematographer
Sivakumar Vijayan, were reported to be a part of the technical team. Vijayan was later replaced by debutant Harish Kannan. A report from
The New Indian Express, dated 2 August 2019, stated that Vikram will be seen in 25 different looks. In December, Viacom18 backed out of the project for unknown reasons, and Lalit Kumar was credited as the sole producer. While it was rumoured to be titled as
Amar, the makers cleared the rumours by announcing the official title as
Cobra on 25 December 2019. The team titled the film "Cobra" because it resembles the pivotal character of snake
cobra. Gnanamuthu, further revealed in an interview to
The Times of India, saying "The protagonist's character and cobra has a link", and revealing anything further would give away key plot details. He added, "Also, since the film is made in Tamil, Telugu and Hindi, I wanted a title that works in all languages. Hence, we zeroed in on Cobra". Speaking to
Ananda Vikatan, Gnanamuthu described
Cobra as a multi-genre film and includes various genres such as
psychological,
science fiction,
thriller and
action. Vikram's character was revealed to be a mathematician and a shape-shifter, who uses mathematics for criminal activities.
Casting In late October 2019, the makers announced that
Srinidhi Shetty, would play the female lead. This film marks her debut in Tamil cinema. Shetty was cast after a successful audition, and Gnanamuthu called her role a "complete contrast" to what she played in the
Kannada film
KGF: Chapter 1 (2018). Former Indian cricketer
Irfan Pathan signed to play a pivotal role in the project. This also marks his debut in Indian film industry. Gnanamuthu had watched several of his
TikTok videos, and impressed by his acting stints he met Pathan at his house in
Vadodara,
Gujarat, who later agreed to be a part of the film. In late October,
K. S. Ravikumar joined the cast and shot for a few days. Gnanamuthu stated that his character will be a "complex" one and "quite integral to the script". and in the same month
Robo Shankar also joined as one of the supporting actors. Ajay Gnanamuthu chose to sign
Shane Nigam for an important role in this flick, after being impressed by his performance in the Malayalam film
Kumbalangi Nights (2019). Theatre personality
Mohammad Ali Baig, was also cast in February 2020. In April 2020, Malayalam actors
Roshan Mathew,
Miya George, and
Mamukkoya were included in the cast. It is the Tamil debut of Roshan Mathew.
Filming Principal photography began on 4 October 2019 in Chennai. While Pathan joined the sets of the shoot on 15 October, Shetty joined only at the end of the month. The former had finished the first schedule of the film on 6 November 2019 in Chennai. On 11 November 2019, Vikram and his team headed to Alleppey for a song shoot, which was completed within two days. By the end of November 2019, the second schedule of filming was completed in Kerala. The third schedule of the film took place in Chennai in December 2019. The makers planned to shoot a few sequences across Russia and Europe in January 2020. Meanwhile, on 17 January, the makers headed to Kolkata to prepare for the third schedule. Irfan Pathan completed his portions for the flick on 21 January, during the fourth schedule. On 6 February, the makers planned to shoot the climax sequence in Russia. On 7 February 2020, the makers shot a crucial sequence at the
Ramee Mall in Chennai. Vikram and Gnanamuthu began filming in Russia in March 2020, despite fears that
COVID-19 might spread. A rapid spread of COVID-19 forced the crew to halt filming and return to India. The film's shoot was further affected due to the
COVID-19 pandemic, as 25% of the shoot is pending as of March 2020. Ajay Gnanamuthu announced he would take a pay cut for the film, in order to help producers during these challenging times. The lack of international travel facilities made it impossible for the team to shoot in Russia, so they created huge sets resembling the country in
Chennai. The team began dubbing the film in October 2020. Filming resumed on 3 December 2020 in Chennai, with Vikram joining the sets. After completing the schedule, the team travelled to
Kolkata on 22 December 2020. However, since Vikram was also involved in the shooting of
Ponniyin Selvan during mid-January 2021, the team decided to shoot a few scenes without him and the production team stated that the actor would join the shoot once his portions were completed. Shetty completed her shoot on 7 February 2021. ,
Russia Ajay Gnanamuthu was unsatisfied with the portions shot on the sets, so the team decided to go back to Russia in mid-February 2021, despite the cold weather. On 22 February 2021, Vikram joined the film's shoot in Moscow, where the final portions of the film were being filmed. Pathan joined them on 26 February 2021. The team filmed a few scenes at
Saint Petersburg State University on 2 March 2021 as part of their final schedule. The team completed the major portions of the film on 5 March 2021. Shooting was delayed, apparently due to Vikram's commitments with
Karthik Subbaraj's directorial
Mahaan (2022) produced by the same production company 7 Screen Studio and the subsequent lock-down implemented by the government to curb the second wave of the pandemic. After the shooting of
Mahaan concluded, the team restarted production on 15 August 2021, with the commencement of a minor schedule in
Kolkata. After the producer's parallel projects and Vikram's other commitments, the team started its final schedule in Chennai on 24 November 2021 and continued for a month. Vikram completed his portions in January 2022, and on 15 February 2022, Gnanamuthu tweeted that the filming was completely
wrapped. == Music ==
