Good chemistry between Shahrukh and Ritesh

In Shahrukh's upcoming venture RA.ONE, Ritesh was the first choice of the filmmaker to play the role of the villain. Though, later Arjun Rampal bagged the role despite the fact that he was suffering from a back ache. Not even once did SRK reserve the role for his so called dear friend Ritesh. Ritesh has not complained about it directly, However inside sources claimed that the actor feels let down by his friend.
