Milkha's most memorable moment arrived at the 1960 Rome Olympics, where he finished fourth in the 400 meters event, narrowly missing a medal. Although he didn't win, his remarkable performance earned him the nickname "The Flying Sikh." This achievement catapulted Milkha to international fame, and he became an inspiration to millions of Indians.

The soundtrack, composed by Shankar-Ehsaan-Loy with lyrics by Prasoon Joshi, plays a crucial role in driving the narrative. Track titles like the high-octane title track Zinda , the motivational Bhaag Milkha Bhaag , and the soulful O Rangrez perfectly complement the film's changing moods, elevating the viewer's adrenaline and emotional investment.
