Arjun Rampal and Suvinder Vicky in Satluj: The Power Axis

Satluj is not only a Diljit vehicle. The film's dread lives in opposing uniforms.

Suvinder Vicky as Sugga

As SSP Surjit Singh Sugga—echoing Ajit Singh Sandhu—Vicky plays institutional cruelty without cartoon volume. Multiple reviews called the performance chilling. He embodies the “system” more than any single monologue does.

Arjun Rampal as Samudra Singh

Rampal's CBI officer arrives when personal investigation has already exacted a cost. The character is less saviour fantasy, more procedural counterweight. Critics treated the casting as adult casting, not glamour injection.

Kanwaljit Singh's Bitta

As a DGP figure inspired by K.P.S. Gill, Kanwaljit represents apex police ideology of the era. His off-screen defence of the film's right to be seen after the ZEE5 pull added another layer to press coverage.

Full roster: cast explained. Historical backbone: Khalra.

Their roles

Arjun Rampal and Suvinder Vicky play pivotal supporting roles in Khalra's story — the allies, officials, and ordinary people orbiting his investigation. Both are known for intense, grounded performances, and critics noted how the ensemble lets Diljit's quiet lead performance breathe.

Why the casting works

Surrounding a transformative star turn with rock-solid character actors is what gives the film its documentary-like weight. Nobody showboats; everyone serves the true story.
