Filmmaker Subhash Ghai, whose repertoire is studded with films like "Karz", "Ram Lakhan", "Khalnayak" and "Pardes", feels that the definition of a "commercial film" has not changed in the Indian cinema dictionary since the 1970s era.

Ghai, who was known for spinning magic on the silver screen in the 1980s and 1990s, made the observation after looking at the list of blockbusters of the year gone by.

"The definition and grammar of commercial blockbuster films has not changed since '70s if you look at last year's blockbusters at PAN India - same," Ghai tweeted on Sunday.

Ghai, who started his directorial career with the 1976 film "Kalicharan", also shared: "Babuji says - when a movie fails, means the director has failed to narrate the story on screen he selected - 95 percent failed last year? why? To study".

In the recent times, Ghai has failed to recreate his cinematic magic with his last few movies -- "Yuvvraaj" and "Kaanchi: The Unbreakable" turning out to be damp squibs at the box office.
