Actor Rajkummar Rao, who is all set to feature in two distinctive roles in "Newton" and a yet untitled movie, says the variety gives him a "good high". "Right from my first film, I have tried to do distinct roles and those that give me a good high. The films that I'm currently working on are also very different from each other and I am thoroughly enjoying working on them," Rajkummar said in a statement. The actor's yet untitled project is directed by Vikramaditya Motwane, and "Newton" is helmed by Amit Masurkar. Rajkummar has begun work on Motwane's film and this is the first time that they have collaborated. The "Kai Po Che!" star will be seen playing the lead role in the film. However, other details have been kept under wraps at the director's behest. He is currently filming for "Newton", a black comedy, in Chhattisgarh. (Source: IANS)
