According to sources, Big B is investing a huge amount of money into Abhishek's forthcoming film Drona. Following Abhishek's top performance in Mani Ratnam's Guru, Amitabh Bachchan obviously wants to make sure no stones are left unturned in establishing his son as the next big superhero in Hindi cimema.

Apart from mobilising finances, Bachchan Sr has been taking a keen interest in the look of the film, in addition to the dexterously executed special effects.

The content of the film is being kept under wraps at the moment, but those in the know say it's an 'out-and-out superhero flick', adding that all efforts are being made to outdo Hrithik Roshan's Krrish.

A source close to the Bachchans says, "Drona is their answer to Krrish. The budget of Krrish was approximately Rs 45 crore and Drona will be close to Rs 60 crore. The Bachchans, along with director Goldie Behl, are making all efforts to overshadow Krrish's superpowers."

A unit member informs, "Krrish has a tough contender in Drona. The first schedule of the film was shot in Prague. Needless to say there have been no limitations as far as the budget is concerned. In fact, one can easily say that the Bachchans are making the film. Director Goldie and producer Shrishti are family friends of the Bachchans, and they're working closely as a team. If Krrish had an aggressive marketing strategy, Drona will have a better one."

Jaya Bachchan and Abhishek play mother and son in the film.

Stringent security measures have been taken on the sets of the film erected in Kuchaman City in Nagaur. However, it's been heard that Abhishek has been practicing stunts for the film and dons a 'European look' with long locks and all.

Which explains all those months when Abhishek was sporting a hair band around town was while he was in the process of grow his hair. When quizzed about the Drona look, stylist Anaita Shroff says, "I have not drawn any inspiration from any superhero for that matter.

"It's an original vision that I had for Abhishek and Priyanka in the film. All that I can say is that Goldie's treatment of the film is completely novel."
