Bollywood superstar Shah Rukh Khan has talked about how he perfected his stammer in the 1993 film 'Darr' and revealed how he used to bounce off crazy ideas to nail his villainous act in the Yash Chopra blockbuster.
SRK, on the docu-series 'The Romantics', said: "I had a classmate who had a stammer and then we did some little study, some BBC documentary where they talked about that people's minds become aware to one sound, and it's like a sharp current."
