The actress, who was lauded for her performance in the Ritesh Batra directorial, took to micro-blogging site Twitter to call "The Lunchbox" team to unite and make it big.
"Back on the road for not so ordinary a weekend in London! The @BAFTAs beckon! Let's do this Team #Lunchbox," she tweeted.
"The Lunchbox", which also stars Irrfan Khan, is nominated in the 'Best Film Not In The English Language' category. The awards ceremony will take place Feb 8 at London's Royal Opera House.
The movie is a unique love story between a lovelorn wife and a lonely man. While it released in India in 2013, it hit the British screens only in 2014.
The movie opened doors for Nimrat in the West. She landed a role in the American series "Homeland" post the 2013 film.
