Shershaah (transl. Lion-king) is a 2021 Indian Hindi-language biographical war drama film directed by Vishnuvardhan in his Hindi debut and written by Sandeep Shrivastava. Produced by Dharma Productions and Kaash Entertainment, the film stars Sidharth Malhotra in a dual role as Indian Army Captain Vikram Batra and his twin brother Vishal, alongside Kiara Advani as Dimple Cheema. The narrative follows Batra’s journey from a young cadet to a decorated officer in the Kargil War, culminating in his martyrdom during Operation Vijay in 1999.

Announced in May 2019, the film marked Vishnuvardhan's entry into Hindi cinema and Malhotra’s first dual-role performance. Principal photography began the same month and concluded in January 2020. Originally scheduled for theatrical release in July 2020, the film was postponed due to the COVID-19 pandemic and premiered digitally on Amazon Prime Video on 12 August 2021.

Shershaah received largely positive reviews from critics and audiences alike, with particular praise for Malhotra and Advani’s performances, the direction, action sequences, cinematography, and music. The writing drew some criticism for its conventional treatment of the biographical genre. The film emerged as a major digital success and became the most-watched Indian film on Amazon Prime Video in India at the time of its release.

At the 67th Filmfare Awards, Shershaah led with 19 nominations, including Best Actor (Malhotra) and Best Actress (Advani), and won 7 awards—among them Best Film, Best Director (Vishnuvardhan), Best Music Director (Tanishk Bagchi, B Praak, Jasleen Royal, Javed-Mohsin and Vikram Montrose), and both Best Male Playback Singer (Praak for "Mann Bharrya") and Best Female Playback Singer (Asees Kaur for "Raatan Lambiyaan"). The film also won the Special Jury Award (Feature Film) at the 69th National Film Awards.

Vishal Batra delivers a TED Talk recounting the life of his twin brother, Captain Vikram Batra. As a child, Vikram displays a fearless nature, once confronting older boys during a cricket game. Inspired by the television series Param Vir Chakra, he expresses an early desire to join the Indian Army.

While studying English literature in college, Vikram is selected for the Merchant Navy, a decision that pleases his girlfriend Dimple Cheema but leaves him conflicted. Opposed by Dimple’s father due to caste differences, the couple’s relationship faces resistance. Ultimately, Vikram decides to pursue his original ambition and joins the Indian Army through the Combined Defence Services Examination.

Commissioned as a Lieutenant in the 13th Battalion, Jammu and Kashmir Rifles, Vikram is posted to Sopore, Jammu and Kashmir. There, he earns the trust of his unit and the local population. During a counter-insurgency operation, he defies orders to save his commanding officer, Lt. Sanjeev "Jimmy" Jamwal, later developing a close bond with him. When a fellow soldier is killed in an ambush orchestrated by militant Haider, Vikram receives permission from Lt. Col. Y. K. Joshi to lead a retaliatory mission. The operation results in Haider’s death.

As the Kargil War begins in May 1999, Vikram cuts short his vacation and rejoins his unit. He famously tells a friend, “I’ll either come back after hoisting the Indian flag in victory or wrapped in it. But I’ll return for sure.” The unit is deployed to the Ghumri base and eventually tasked with recapturing Point 5140. Using the codename "Shershaah" and the victory signal "Yeh Dil Maange More!," Vikram leads a successful assault without casualties, earning public and military recognition. He is promoted to the rank of Captain.
