"Sunn toh liya hai aapne ab apni aankhon se dekh bhi lo (You've heard it, now see it too), " he added with a mini-poster that reads "'Gangs Of Wasseypur' releasing 8th August, 2012".
The movie is an extension of "Gangs of Wasseypur", which released June 22 to much critical acclaim and also turned out to be a box office bonanza.
Earlier, the release date of the second part wasn't announced.
Both the parts were screened at 65th Cannes International Film Festival, and were applauded by international film aficianados.
The first part narrates the story of Sardar Khan and Ramadir Singh, based on the real life story of Shafi Khan and Surya Dev Singh, both of whom were rivals and are no longer alive.
Part two of the movie is essentially the story of Sardar Khan's son Faisal Khan, who is Faheem Khan in real life. Faheem Khan is alive and in the Dhanbad jail currently.
According to insiders, the makers of the film wanted to sort out all possible issues which could act as a roadblock, before announcing the release date.
