Shahrukh Khan is a bigger super-star than AK and SK combined.
He's moved away from the movies that defined him or else like Salman he could stick to one genre and rake in 250-300 crore movie every year. Rather he's experimenting with movies Ra.one, Raees, Fan, Biloo Barber. He's not just putting his reputation at stake but also involved with these projects as a Producer.
Salman will fade away in a few years when the genre he does will lose its charm. Just like Govinda had his time in the sun in the 90s or Akshay with his comedies is churning out flops after flops atm. Glad he moved to doing more serious movies now though like Baby, Special 26.
