Hrithik Roshan is putting in a lot of efforts for his upcoming release, ‘Super 30’. The actor was reportedly in Mumbai, busy with back to back night shift schedules, shooting for the climax of the movie. Since the film is scheduled for January next year, the ‘Krrish’ star is expected to fly out of the city this weekend for the next round of ‘Super 30’. Duggu will essay the role of mathematician Anand Kumar in this film, being directed by Vikas Bahl. A lot of curiosity surrounds the biopic, with Hrithik losing weight and growing stubble for his character.
