While a close pal of the bearded actor suggests he has been doing this small roles in the above mentioned films because he could not say NO to it's makers as he was returning their favour.
It is now learnt that Kunal has jumped from short roles to short films. He is acting in a short film called Linger. He won't stop at Linger and is about to sign to more short films which have got him very excited.
However, the close pal further adds that it is not that Kunal doesn't have roles as main lead in full length feature films. He shall be seen next in Anurag Kashyap's Doga and Navdeep Singh's(Manorama Six Feet Under) yet untitled next.
