New Delhi: The wait to get a glimpse of the storyline of “Baar Baar Dekho” was over on Wednesday morning with the release of the movie's trailer. It gives a dekko into the love saga -- told through time travel -- and portrayed onscreen by Katrina Kaif and Sidharth Malhotra. The trailer has it all --- love, romance, music, dance, even an elaborate wedding sequence -- but what stands out is the theme of time travel. The makers of "Baar Baar Dekho" had shrugged off reports that the movie was only a narration of what happens in the life of a person from 18 years to 60. But the trailer has given out that Sidharth's character goes forward in time in some days. The trailer starts with Jai (Sidharth) living a perfect life with his love Diya (Katrina), but their life takes a drastic turn when Jai develops cold feet and leaves Diya before their wedding. It is then that he travels back and forth across time, and sees what the future holds for him. That is when he decides to mend his mistakes to relive his life with right decisions. The film's trailer is not just high on emotional and entertainment quotients but style as well. Katrina is seen flaunting three styles -- from a short-haired professional look to carefree young girl and even a peppy bride. Sidharth is also seen in different looks. He sports a rugged look, and is also seen in a mature get-up with a beard and has also sported the look of a young professional. Produced by Excel Entertainment and Dharma Productions, the film is helmed by debutante Nitya Mehra. It is slated for release on September 9. The trailer has won kudos from the film fraternity. Director Sujoy Ghosh tweeted: "Saw the 'Baar Baar Dekho' trailer. Every trailer is getting better and better and raising the bar", while Neil Nitin Mukesh shared: "What an outstanding trailer of 'Baar Baar Dekho'."
