All's not well between Shah Rukh Khan and the director of Ra.One, Anubhav Sinha.

The two recently had a showdown when Sinha went to Mannat to check on SRK's health. The actor has been nursing a cold and fever and wasn't in the best of moods.

Somehow, an argument over certain creative differences regarding an important scene in the film, ensued. The actor didn't like the director's idea and shot it down.

Anubhav initially defended his position, but finally backed down and agreed to go with the actor's vision.

SRK's growing frustration with the film is reflected in his latest tweet "Random thought: It's so difficult to give form to your vision, when so many people are not only on a different page but reading some other book."

Maybe, maybe not.
