Bollywood lacks three very essential skills - screenplay writing, technology and discipline - says superstar Shah Rukh Khan, who has been in the industry for almost two decades.

"Hindi films lack in three very important aspects of filmmaking. The first amongst them is screenplay writing. We need to understand the format and adhere to screenplay writing technique like them (Hollywood).

The sooner Indian filmmakers realise that screenplay writing is not an art form but a science, the faster our films will globalise, " Shah Rukh said Friday at the India Today Conclave.

"Secondly, I feel so odd that on one hand we have the biggest software developing industries of the world, but somehow we are lacking behind in it's usage in India. We have the means to buy the machines, but we don't have mechanics to stand by them. That is a big investment we are looking for from Hollywood."

"We need our own people who can make us our own cheaper, better, faster software for visual-effect teams, " he added.

"The third important thing that we need to learn is the discipline with which they (Hollywood) do their business. It does exist in other sectors, but it is lacking in the film industry."

"If our industry wants to thrive economically, we also need to figure out and learn ways of selling our dreams to the largest number of people in the shortest span of time. We need to learn the science of marketing from them, " he said.

The actor also felt that if one didn't understand the importance of these aspects, sooner our young audience will stop watching our own domestic product.

At the same time, Shah Rukh felt that Indian filmmakers need to maintain their own individuality.
