Bollywood actor Saif Ali Khan who has garnered a lot of love from the masses for his performance as a determined cop in action drama `Vikram Vedha` said that the film demonstrates how challenging it can be to alter one`s point of view of good and evil.

Saif had put great effort into his character. From vigorous practice with real guns to understanding the sounds and mechanism of shooting a real gun, the actor went into the skin of the character to showcase realism on the celluloid. He adopted the way they hold guns and the way they raid buildings inhabited by gangsters.
