Production started in second half of 2013. Sonakshi Sinha performed some action scenes in the film.
Charmy Kaur shot for an
item song "Gandi Baat" for the film in June 2013. Kannada actress
Ragini Dwivedi made her Bollywood entry (only Bollywood film at moment) in the item song "Kaddu Katega" which also featured Scarlett Mellish Wilson and only her Bollywood film at the moment. The film was first titled
Rambo Rajkumar which is also the name of a veteran stunt director from south India. According to reports, the makers of the original
Rambo series had copyrighted the word Rambo making it unavailable for usage by other filmmakers. As a result, the makers decided on a title change for the film. However, since the film's title is already known among the audience, the makers decided on dropping a few letters from the title, rechristening it to
R... Rajkumar. After the film's title change, Shahid Kapoor's character in the film, which was Rambo Rajkumar initially, was also changed. During its filming, Kapoor narrowly avoided serious burns during a stunt sequence. Song sequence was shot at
Great Rann of Kutch. While filming the movie,
Srihari complained of giddiness and was rushed to
Lilavati Hospital. Due to a prior liver ailment, he died in the hospital on 9 October 2013. After the film's release and subsequent success, the
Academy of Motion Picture Arts and Sciences, which oversees the famous
Academy Awards, sent a formal letter to producer Viki Rajani asking for a copy of the film's script to be kept in the Oscar Library. This is the fifth
Bollywood film, after
Lagaan,
Heroes,
Rock On!!, and
Guzaarish, to be requested for this honour by the academy. Speaking of the request, Viki Rajani said, "It's a privilege that our movie script has been recognized internationally and it's an honour for us to be a part of the archives at the Academy Library. The movies was loved by the audience and has done well at the box-office. This is another happy moment for the entire team." Director
Prabhu Deva, speaking of the request, said, "Making this movies has been a fun experience and this honour tops it all. What more can I ask for." For the song Gandi Baat, Sonakshi Sinha refused to wear a bikini while emerging from the pool of water out of comfort and respect. Instead, Sinha wore a saree for the sequence of the song. ==Music==
