Ranveer Singh Bhavnani (born 6 July 1985) is an Indian actor who appears in Hindi films. He is the recipient of several awards, including two Filmfare Awards, and is among the highest-paid actors in the country. After completing a bachelor's degree from Indiana University Bloomington, Singh returned to India to pursue his career in films. He made his acting debut in 2010 with a leading role in Yash Raj Films' romantic comedy Band Baaja Baaraat.

In January 2010, Singh was called for an audition by Shanoo Sharma, the head of the casting division for Yash Raj Films. They informed him that it was for a lead role in their film titled Band Baaja Baaraat, a romantic comedy set in the world of wedding planning. Aditya Chopra, the vice president of the company, later saw the audition tapes on video and was impressed by Singh's acting, and decided that he fit the part of Bittoo Sharma, the hero of the film. However, the director Maneesh Sharma needed some more convincing and he was called for a few more auditions over the next two weeks until they were completely convinced of his caliber. After the two weeks of testing, Singh was confirmed for the role of Bittoo, with Anushka Sharma playing the female lead.  Singh described the role of Bittoo Sharma as a typical Delhi boy. To prepare for the role, he spent time with students at the Delhi University campus. Prior to the release of the film, trade analysts were skeptical of the film's commercial potential, citing the middling response to Yash Raj Films' last few productions, the lack of a male star and the fact that the female lead, Anushka Sharma, was by then an "almost-forgotten" actress. However, Band Baaja Baaraat went on to become a sleeper hit. Singh's portrayal of Bittoo was praised, with Anupama Chopra of NDTV writing that Singh was "pitch perfect in the role of the uncouth but good-hearted small town slacker who is a bit of a duffer when it comes to matters of the heart." The film earned approximately Rs214 million (US$3.3 million) at the domestic box office. At the 56th Filmfare Awards, Singh won the award for Best Male Debut.  Following Band Baaja Baarat, Singh signed on for Ladies vs Ricky Bahl, a romantic comedy produced by Chopra and directed by Maneesh Sharma. He played a conman Ricky Bahl who cons girls for a living but finally meets his match. The film co-starred Anushka Sharma, Parineeti Chopra, Dipannita Sharma and Aditi Sharma. According to Singh, the title character had various avatars in the film, including a chirpy, entertaining side and a sinister side. Nikhat Kazmi of The Times of India wrote, "Ranveer is, well Ranveer: your average Joe kind of hero who looks convincing enough as Sunny, Deven, Iqbal, Ricky, his sundry avatars." Commercially, Ladies vs Ricky Bahl earned Rs370 million (US$5.7 million) domestically.
