Everything felt so real and I was bowled over by the city's people. Shooting in live locations, especially amid lovely people in a culture-rich city, enhanced my performance to a great extent," she said, adding she had a blast bonding with people of Lucknow.Talking about her co-star Rajkummar, with whom she had teamed up for the first time, Shruti said: "We got on like a house of fire. It was fun working with Rajkummar, and the reception to the trailer is proof to our chemistry and how much we enjoyed working together."Shruti recently walked out of Tamil historic film "Sanghamitra", citing reason that she had not received a bound script or a proper schedule.She spent nearly six months prepping for the role of a warrior, training in sword-fighting.Shruti believes all the hard work will not go waste."No amount of learning goes waste. It adds to building your skill set and intellect. I'm sure I'll get to use everything I learnt for some other project," she added.
