It's a known fact that Bollywood's national award winner Rajkummar Rao is in demand these days. He is one of the busiest young guns of the current lot. He has multiple films lined up in the pipeline for which he has been shooting round the clock.

But that doesn't mean that he wouldn't have time for his mentor Mahesh Bhatt. Rajkumar has repeatedly acknowledged Mahesh's contribution in his career and hence as and when comes the time that he can return the favour, he leaves no stone unturned.

Hence when recently when Mahesh called him to play a key supporting role in his next starring Emraan Hashmi, 'Hamari Adhuri Kahani' he didn't think for a second even. He immediately agreed to do the part as he confessed that he cannot say 'no' to Mahesh Bhatt.
