Filmmaker Sanjay Gupta, who has focussed all his attention on his much-publicised film "Jazbaa", says the script for his next project has been finalised.

Keeping up with the trend of announcing projects and developments on social medium, the filmmaker took to micro-blogging site Twitter to share the news.

"I'm glad that the script of my next film is locked. Post that I will be taking on one of the biggest challenges of my life courtesy @akash77," he tweeted.

Action film "Jazbaa", which stars big names like Aishwarya Rai, Irrfan Khan and Priya Banerjee, is being shot and is expected to release later this year.
