Mr Perfectionist has just got another bellyache. Or is it one he's giving others, again?

In the recent past, his production of Taare Zameen Par, saw the original director and writer of the film, Amole Gupte, being sidelined and the producer-star of the film, massively rewrote the film and took over the reins, too.

He gave due credit to Gupte, but the scrap caused a lot of heartburn to Gupte, naturally. It was small consolation that the film was appreciated very much by the audieneces as well as critics.

Now, Aamir Khan's production of Delhi Belly seems to have caused heartburn and a bellyache too. The first to the original director of Delhi Belly, and the second to Aamir Khan, to be sure.

Or is it that Aamir is giving a lot of bellyaches to just about everyone around?

These pre-production aches and post-production heartburns are not usual for Mr Khan, and he would probably have quite a stomach upset if he didn't play Mr Perfectionist all the time.

While the directorial responsibility in TZP changed hands when the film was nearly complete, Delhi Belly has seen a change at the helm even before it has gone on the floors.

The original choice to direct Aamir Khan's quirky and crisp sex comedy was Swedish director Robert Nylund. Nylund is nyet nyet already!

Delhi Belly has a new director in the chair already and likely to have a change of language, too.

Confirmed a source close to Delhi Belly, "Robert Nylund has been replaced by Abinay Deo who is veteran actors Ramesh and Seema Deo's younger son -- the elder one, Ajinkya, is a recognised Marathi and Hindi actor."

The source also informed that the film was originally going to be in Hindi when it was to be directed by the Swedish director. Amusingly, it will now be in English."

It has turned out to be big break for the bright spark ad-filmmaker who has already notched up high-budgeted star-studded Pepsi and Cinthol commercial spots.

Shah Rukh Khan, Ranbir Kapoor and Deepika Padukone starred in his recent Pepsi ad with the 'Youngisthan' theme while Hrithik was the lead in the Cinthol ad.

Added the source, "In an instant replay of what happened between Aamir and Amole Gupte during TZP, Aamir couldn't see eye to eye with the Swedish director. Aamir was very impressed by Abhinay's ads. When they met, he found Abhinay to full of do-able ideas."

So, the deal clicked. Reportedly, Abhinay has been asked to direct Delhi Belly on the lines of Guy Ritchie's heist-caper Snatch. "It would be a very naughty and sexy comedy unlike anything one would expect from Aamir. And, yes, he's likely to play a part in it."

So, then, there is much to look forward to with this project. After the bellyache break.
