A lot of hard work plus the viral fever has left director Karan Johar completely exhausted these days. Yet the director is busy with with three projects. He is currently working on the postproduction of his film Dostana that is being directed by his erstwhile assistant Tarun Mansukhani.

Meanwhile he is busy with the screenplay of his next film My Name is Khan "We will start filming on the 15th of December in Los Angeles. The ensemble cast has recently been finalized and we have started the process of song recording.

I'm going for my final location recce with my Director of Photography, Ravi K. Chandran, Production Designer, Sharmishta Roy and Costumes Designers, Manish Malhotra and Shiraz Siddique."

Karan says this always puts him in immense pressure. "To say I'm nervous is still understating my state of mind because there are some moments in the day where I do feel extremely incapable of handling his complex film.

But I suppose venturing into new territory and tapping into the right tone is a challenge I look forward to taking on" he says.

Karan further reveals "My name is Khan is all about Rizvan Khan who suffers from Aspergers Syndrome (high functioning Autism)."

He says that his screenplay writer Shibani Bhatija, has researched this disorder very accurately. "I can't wait to see Shah Rukh portray it.

The message that runs right through the film is in strong support of humanity, which at the end of the day is the only way to rise above any of the cultural or religious differences that continue to engulf us" he informs.

He is currently working on his next Wake Up Sid! With Ranbir Kapoor and Konkona Sen Sharma. "We plan to start filming it in a day or two and Ayan the director is heading towards a nervous breakdown," he concludes.
