Surely why not but his style may be different than Rajat's style.After all he is not the real grown up Rajat.And we should like that particular style,that's more imp.
Let me confess that I am a huge fan of Rajat Tokas and simply admire his each and every style of acting,so I will be certainly partial with any one else.That is entirely my fault and not Anas ka problem.
But then if you ask people whether Gabbar was more impressive when done by Amjad Khan or Amitabh ,then majority of them will certainly vote for Amjad Khan,does this mean that Amitji did not do good acting in RGV's aag,no way, he is the star of the century.The same funda is applicable here also.
The question is whether we ready to imagine Anas in place of Rajat and as for me,I am not yet ready for it!Sorry the problem lies with me.
