"Mary Kom" fame director Omung Kumar has thanked actor Randeep Hooda, who lost 28 kg in just 28 days for the upcoming film "Sarbjit".

"Sarbjit" is a biopic on Sarabjit Singh, an Indian farmer who was convicted for terrorism and spying in Pakistan and was sentenced to death. He was attacked by inmates at a prison in Lahore in April 2013 and died a few days later.

Kumar thanked the "Highway" star, who will essay the role of Sarabjit, for taking Kumar's "vision" of the character "ahead".

"@RandeepHooda thank you for taking my vision ahead. #Sarbjit releasing 19th May 2016," the director tweeted on Saturday.

The film, which also stars actors Aishwarya Rai Bachchan and Richa Chadha, is slated to hit the screens on May 19, a day before it was scheduled to hit the screens.
