Recently, there was an article in TOI mentioning that SRK might be playing a small part in Krrish 3, which is best buddy Hrithik's super-hero flick. However, looks like this was either a false rumour or there have been some change of plans. Rakesh Roshan confirmed that this will not be happening. "There is no talk of SRK doing a cameo in KRRISH 3," says the filmmaker.
However, it is believed that SRK will still assist the Roshans in the special effect category as he had good ones in his own RA.One and is now very much an expert in this field..too.
