Sardar Udham is the soundtrack to the 2021 film of the same name directed by Shoojit Sircar, starring Vicky Kaushal as Udham Singh (on whom the film is based on), a freedom fighter from Punjab who assassinated Michael O'Dwyer in London to avenge the 1919 Jallianwala Bagh massacre in Amritsar.

[2] Moitra composed the film score during June 2020 as a part of the four-phase production process organised by Sircar during the COVID-19 lockdown period.

[3][4] Before the film began production, Moitra recorded an instrumental track considering the state of Udham Singh's mind in that music space.

[6] In the film's review published in the magazine The Week, Aiswarya Venugopal stated about the music, saying "the six instrumental tracks composed by Shantanu Moitra, flows perfectly as it depicts different phases of Udham's life".

[8] A reviewer from Deccan Herald too praised the exclusion of songs in the film as it caters "realistic storytelling".
