"Sunny Deol's action sequence is left to be shot. Last schedule, which will be shot in Mumbai, will get over by July 22. It has some unusual action sequences by Sunny Deol," said Sharma, who has earlier directed Sunny in Gadar - Ek Prem Katha.
He further added: "The film has shaped up very well and we will be releasing the film this Dussehra (October 11)."
Sharma, known for making lengthy films, says most blockbusters are lengthy.
"If a film can hold back the audience for three hours, then it is a hit. If you go by history, all lengthy films were blockbusters including Mughal-E-Azam and Dilwale Dulhania Le Jayenge, among others," he said.
