WEB DESK: Baar Baar Dekho starring Katrina Kaif and Sidharth Malhotra is about time travel. No, not sci-fi, this is emotional time travel the way only Bollywood can do it.

The Baar Baar Dekho trailer released on Wednesday morning, but only after we watched Sidharth and Katrina romancing on a beach and dancing off to Kala Chashma.

The trailer begins with the perfect equation of love: Jai (Sidharth Malhotra) + Diya (Katrina Kaif) = Love. Now only if life was as simple as Math. Between Katrina and Sidharth’s love comes life. He develops cold feet, she walks out. And then, the time travel comes in.

Suddenly, the mathematical genius Sidharth is given a short and not so sweet view of his life. In a few days, he will see the highlights of his life whizzing past him. That means he will get another chance to fix things.

He can talk to Diya, he can let his loved ones know that he cares for them and he will get to dance to Kala Chashma with Ram Kapoor, Rohan Joshi, Rajit Kapoor, Sayami Ghosh and, of course, Katrina Kaif.

As everybody in India — and now Sidharth — knows a wedding can fix everything. But before the dancing can begin, we see Katrina looking equally beautiful as a nerd and as a goddess in a bikini. And those rock-hard abs, we want them now.

Sidharth looks convincing as a bemused man whose life is going way too fast.

The film lands on September 9 this year. Baar Baar Dekho has been directed by Nitya Mehra and story is by Sri Rao. It has been produced by Farhan Akhtar, Karan Johar and Ritesh Sidhwani.
