Filmmaker Ketan Mehta says his forthcoming venture 'Rani Lakshmi Bai' will require use of VFX in order to do justice to the war sequences in the biopic. Actress Kangana Ranaut will be seen in the role of Rani of Jhansi, one of the leaders of the first Indian war of Independence in 1857.

The 'Queen' star would undergo a lot of physical transformation, including, learning sword-fighting and horse-riding.

When asked if the film would require a lot of VFX work to recreate the era, Mehta told PTI, "Yes, obviously. All films today use VFX and the war sequences in our film will also require to be digitally enhanced. It is going to be visually rich, highly dramatic film."

The filmmaker has in the past helmed movies like 'Manjhi: The Mountain Man', 'Rang Rasiya' and Aamir Khan starrer 'Mangal Pandey: The Rising'.

The 'Rani Lakshmi Bai' biopic would see the director try new things but Mehta insists he does not see the film in terms of high budget or as his 'magnum opus.'

"I don't see films like that. To me, it is one of the most fascinating stories in the world. The story of Rani Laxmibai is worth telling and putting on the big screen."
