The 63rd National Awards this year appear to have been largely hijacked by Bollywood, as most of the winners are the mainstream commercial movies and stars, while the regional and art films have taken a backseat.

Megastar Amitabh Bachchan won his fourth National award for Piku, while it was a second consecutive best actress win for Kangana Ranaut at the National Film Awards announced on Monday, which saw Bollywood dominate in major categories, barring the top prize that went to multilingual offering Baahubali.

Big B won the best actor honour for his turn as a hypochondriac father in the road-trip family drama.

He has previously won the National award for Agneepath, Black, and Paa.

Ranaut, who turned 29 last week, was declared the winner for her endearing dual turn as Tanu, a troublesome wife and Haryanvi sportsperson Datto in the romantic comedy Tanu Weds Manu Returns.

The actress called it the best birthday gift, especially since she shares the honour along with Bachchan.

“It is the best birthday gift I could have got. I am thrilled and feel blessed especially since Mr Bachchan is the best actor with me,” Ranaut said in a statement.

This is the third trophy for Ranaut at the National Awards, and she won best actress for Queen last year and earlier for best supporting actress for 2008 film Fashion.

SS Rajamouli’s magnum opus Baahubali was named the best feature film winner by filmmaker Ramesh Sippy, who headed a 11-member jury, even as last year’s much-appreciated Masaan had to content itself with just a best debut director award for Neeraj Ghaywan.

Baahubali star Rana Daggubati said: “I am thrilled. We took a risk and attempted something different with it. Now with this award we feel honoured."

Sweeping historical romance Bajirao Mastani, starring Ranveer Singh, Deepika Padukone and Priyanka Chopra, helped its director Sanjay Leela Bhansali win the best director honour, besides bagging five more honours.

Sharat Katariya’s debut Dum Laga Ke Haisha, a '90s set drama in Haridwar about the romance between a mismatched couple, was named the best Hindi film.
