Actor Rajkummar Rao chose to work as a labourer for a day to prepare for his role of a commoner in his upcoming film 'CityLights'. The 29-year-old actor decided to step into the shoes of a poor man to experience the struggles he undergoes to make his ends meet. In the process, he posed as a menial worker and went door to door seeking jobs in Mumbai. "Rajkummar went looking for a job near Santacruz station and asked if he could get some work but was denied. Later he landed up at a construction site nearby. The contractor offered him to work at a wage of Rs 100 a day and he agreed to work," a source close to their production team said in a statement. "Rajkummar actually slogged and worked hard to earn Rs 100. This scene will even be seen in the film," the source said. In the film, Rajkummar plays the role of a rural trader who migrates to Mumbai in search of a better life and then goes on to face the challenges of an urban culture. 'CityLights', directed by Hansal Mehta is the story of every common man who, in search of a better livelihood, migrates from rural areas to urban cities. The film, an official adaptation of British film 'Metro Manila', is scheduled to release on May 30.
