Mumbai, Jul 23 (PTI) "Let's do it for real" was the only brief that South Korean action director Sea-Young Oh had for actors Lakshya and Raghav Juyal while working on "Kill", which has been hailed as one of the most unique action movies to come from India. The story, produced by Karan Johar's Dharma Productions and Guneet Monga's Sikhya Entertainment, is set on a moving train as one man and his friend take on a group of violent goon who board the train and start looting and killing passengers randomly. Oh has emerged as Bollywood's favourite action director in recent years and has worked with stars like Shah Rukh Khan, Hrithik Roshan and Salman Khan on movies such as "Fan", "War" and "Tiger 3".

The action master, known for his work on Korean as well as international projects such as "Parasite", "Snowpiercer", "Avengers: Age of Ultron", "Ode to My Father" and "Sympathy for Mr Vengeance", said "Kill" director Nikhil Nagesh Bhat wanted action sequences to convey the vulnerabilities of an ordinary man bent on revenge. "It really took months to design the action sequences..

. Lakshya and Raghav performed action so well that I didn’t have much briefs to give them. There was only one thing I had to request to them: 'Let's do it for real.

Not acting like it is real, but do it literally with real hits and punches'," Oh told PTI in an interview. The action in “Kill” makes excellent use of the train’s narrow corridors, restricted spaces, berths, and toilet seats, and the South Ko.
