Bollywood in 2015: Watch out for epic costume dramas

From "Bajirao Mastani" to "Mohenjo Daro" -- it looks like 2015 will be an epic year for Bollywood. Several filmmakers have lined up big budget spectacles that go back in time.

Here's looking at the big budget epics of 2015:

* "Bajirao Mastani": Set in the 17th century, Sanjay Leela Bhansali's quasi-historical featuring the "Goliyon Ki Raasleela Ram-Leela" trio of Ranveer Singh, Deepika Padukone and Priyanka Chopra, is one of the most expensive Hindi films to be produced. Bhansali spares no expenses to tell the love story of Maratha Peshwa Bajirao and his liaison with his two wives.

* "Detective Byomkesh Bakshy!": In this movie set in Kolkata of the 1940s, Dibakar Banerjee recreates the intrigue of the era through painstaking care for details. Sushant Singh Rajput changes his body language completely for the movie, said to be Banerjee's most expensive film to date.

* "Bombay Velvet": Ranbir Kapoor amd Anushka Sharma relive 'Bombay' in the 1960s in this large screen adaptation of Gyan Prakash's "Mumbai Fables". The bygone era of Mumbai was recreated in Sri Lanka. The film is reputed to have gone over budget.

* "Hawaizaada": The period film features Ayushmann Khurrana in the role of a 19th century scientist and aviation pioneer Shivkar Bapuji Talpade. It is directed by Vibhu Puri.

* "Mohenjo Daro": Ashutosh Gowariker's fourth period film after "Lagaan", "Jodhaa-Akbar" and "Khelein Hum Jee Jaan Sey" takes Hrithik Roshan back to the Indus Valley civilisation. With his modern body language, it would be interesting to see Hrithik turn the clock back to a time when perhaps there were no clocks.
