<P> The first trailer of the film was all set to be screened at 66th annual Cannes Film Festival in mid-May 2013, however it was delayed due to Soundarya's dissatisfaction over the final cut of the trailer . The first teaser trailer was released digitally on 9 September 2013, coinciding with Ganesh Chaturthi to mixed response; while fans of Rajinikanth were satisfied, others criticised it for its "poor visual effects". It was also noted for its similarities to the teaser trailer of Soundarya's shelved animation venture Sultan the Warrior, that was also supposed to feature Rajinikanth . Nevertheless, it was viewed over 1 million times on a single day, establishing it as one of the most anticipated film teasers in the history of Tamil cinema . Soundarya also announced that a second trailer would be released, which would feature Padukone prominently, and unlike the first trailer, it would have sound and dialogues . The trailer was released in Tamil, Telugu and Hindi on 9 March 2014, the same day of the audio launch . </P> <P> In 2012, the producers struck a deal with Karbonn Mobiles, an Indian telecommunication firm that will involve Kochadaiiyaan merchandise worth ₹ 5 lakh (US $7,300) with screen savers and images from the film along with the trailer, behind the scenes shots, signature tune of the film and lead actor's signature on back cover of phones . However, delays in the film caused the clause to be modified . Sudhir Hasija, chairman of Karbonn, said, "We will roll out a million handsets by February - end or first week of March 2014 with a pre-loaded app for the movie . All the handsets will come with the signature of Rajinikanth . This is the first time any mobile handset maker is launching products with an augmented reality app ." The promotional tactic is an extension of Eros' alliance with Karbonn, wherein the latter will make a million special - edition phones . A company called InGage Technologies have done its complete development . Using augmented reality, they set interactive Kochadaiiyaan hoardings in association with Karbonn Mobiles . Eros has deployed 500 interactive hoardings across India . People will have to stand in front of the hoarding and send an SMS to activate the hoarding . Karbonn stated that an estimate of 400 hoardings would be put up across the country, majority in southern states of India . Hoardings and banners of the film will be displayed at 3,650 Bharat Petroleum stations across South India . </P> <P> On 21 April 2013, Soundarya revealed a first fully 3D rendered picture, which shows Rajinikanth in two different avatars . It was also announced that a "making - of - the - movie" video would be released, where a song featuring Rajinikanth's voice would be used . It was shown nearly a year later on 9 March 2014 to the audience of the music launch event . In mid-March 2014, the franchise was expanded further as Hungama Digital Media Entertainment and Gameshastra launched two mobile games based on the film available for download on mobile platforms, called Kochadaiiyaan: Kingdom Run and Kochadaiiyan: Reign of Arrows . By mid-May 2014, the games surpassed the mark of one million downloads across the iOS App Store, Google Play and Windows Phone Store . </P> <P> iPlay's director Rave Shankar and his team had approached the film's producers to screen the theatrical trailer in 5 - D format at Phoenix Market City Mall in Velachery, Chennai . The producers provided the 3 - D print of the trailer at no cost . Shankar and his team worked for about 10 days to get the synchronization of the chair movements, sprayings and light effects for the trailer . The experience for viewers was defined such that the chairs quake and rumble as the scenes of war appear and wet sprays are sprinkled on the audience when the character Kochadaiiyaan rides on a dolphin in the trailer . </P>
