Narrating a fictional story in `Shamshera` meant that director Karan Malhotra could take certain creative liberties. However, with the Ranbir Kapoor and Sanjay Dutt-starrer set in 1871 against the backdrop of the British Raj, the director made sure that the film remained authentic to the period. For an action sequence that sees Kapoor’s character fight the baddies on a moving train, Malhotra and the production design team created an approximate 400-foot train resembling the ones prevalent in the 19th century.
