It looks like Shirish Kunder has already started the promotion of his upcoming ambitious movie "Joker". He posted few of the exclusive pictures of the film cast from the sets of his ambitious sci-fi 3D movie on his Twitter page, which is slated for the September 12, 2012 release worldwide.

"Joker" is the second movie to be directed by Shirish Kunder after "Jaan-E-Mann" that was realised in 2006.

"#JOKER poster has not been released yet. All the pictures you have seen so far are On-Location Shooting Stills from the Sets of," tweeted Kunder.[Check out the pictures of star cast from the sets of "Joker "]

The movie is produced by his wife Farah Khan and Akshay Kumar himself along with UTV.  Akshay owns Hari Om Entertainment and Farah owns Three's Company production house.

"Joker" is the first movie for Akshay to be filmed in 3D movie format; it will come in 2D as well.

After her much-talked-about debut in Salman Khan starrer "Dabangg", the Bollywood town has been hearing a lot about Sonakshi Sinha. "Joker", marks her second movie with the Akshay Kumar, with whom she acted with in "Rowdy Rathore".

Besides, Sonakshi and Akshay, the movie also features Shreyas Talpade, Minissha Lamba, Gurpreet Ghuggi, Asrani, Sanjay Mishra, Vindu Dara Singh, Pitobash, Alexx ONell and Farah Khan. Chitrangda Singh will also be seen grooving to an item number.

Earlier, Kunder tweeted, "Joker is a Human Drama. A tale of a bunch of Underdogs fighting for victory. Treated throughout with kickass humor. And some Sci-Fi :-)."

The fate of "Joker" will determine Kunder's next move, as his earlier films failed to do well at the box office.
