Ranbir, Katrina starrer Jagga Jasoos, being reshot.

Anurag Basu's quest for perfection may see portions of his upcoming film, the Ranbir Kapoor Katrina Kaif starrer Jagga Jasoos, being reshot.

We have learnt that the director wants to improve on some of the scenes he has already canned.

Mirror had earlier reported that Ranbir had to furiously work out to lose weight to transform from Bombay Velvet's beefy street fighter to a lanky 18-year-old for the first schedule of Jagga Jasoos that took place in-between the ongoing shoot of Bombay Velvet.

Revealed a source close to the production, "Around 20 days of shooting has been completed with Ranbir and Katrina. But Anurag feels that he can do better and will be reshooting some portions."

However, the reshoot will not hamper the upcoming schedule of the film. "Anurag will accommodate the changes in the second schedule without extending it.

He knows that after Barfi, expectations from him and Ranbir have increased and he is determined to make an even better film without any creative compromises," adds the source.

Buzz is, the film is a musical which revolves around a gifted teenage detective's search for his missing father. It will have 20 odd songs composed by Pritam who had also given the Barfi! score.

The film was earlier scheduled to wrap up by May 2014, but now it's release has been pushed forward to May 2015. Anurag can afford to spend some more time on the shoot.

When contacted, Rucha Pathak, Senior Creative Director of Disney UTV, producers of the film, said, "Completely baseless.

We are extremely happy with the way the shoot has gone so far, so the question of a reshoot does not arise."
