Co-star Sonakshi Sinha took to Twitter to inform about the same and said the injury did not deter the "Bombay Velvet" helmer from continuing the shoot.
"Today the villain became a hero on the sets of #Akira! @anuragkashyap72 takes a fall, injures himself and gets right back up to shoot! Hero," Sonakshi tweeted.
"Akira", directed by AR Murugadoss of "Ghajini" and "Holiday" fame, is a remake of the 2011 Tamil film "Mouna Guru".
The film also stars Konkona Sen Sharma, Amit Sadh, Raai Laxmi and Sonakshi's father Shatrughan Sinha.
