Set in the 1980s and 1990s, the crime saga will be a complete package of action, drama, politics, police and betrayal.
"'Mumbai Saga' is the title of my new film. It's an epic crime saga set in the 1980s and 1990s," Gupta posted on his Twitter page.
"'Mumbai Saga' is my most ambitious film to date. Action, drama, deciet, betrayal, powerplay, politics, crime, cops and gangsters are the keywords," he added.
The 43-year-old, who is known for films like "Kaante" (2002) and "Shootout At Lokhandwala" (2007), is also planning to cast actors like John Abraham, Sonu Sood, Anil Kapoor, Manoj Bajpayee and Tusshar Kapoor from his last release "Shootout at Wadala", in this film too.
"For now most of the cast of 'SAW' will be retained in 'Mumbai Saga' and some new will also join. Too soon to reveal more. @SonuSood, can't wait to start bro. So miss being on set with all you guys. We'll rock n roll again," Gupta further posted.
