Saif Ali Khan and Jimmy Shergill’s characters in Bullet Raja are very similar to that of Paul Newman and Robert Redford’s roles from ‘Butch Cassidy and the Sundance Kid’, says director Tigmanshu Dhulia. Incidentally, “Butch Cassidy and the Sundance Kid” happens to be one of Saif’s favorite movies and the actor plays a trigger-happy protagonist in the film.
