Director-Producer Sajid Nadiadwala believes that the success of a film depends a lot on the story as well as the cast of the movie, but the budget also plays an instrumental role.

The 2014 hit film, 2 States, which was made on a budget of ` 25 crore, became a blockbuster after it grossed ` 110 crore at the box office.

on Similar lines, Heropanti (2014) was made for ` 15 crore, but it earned around ` 55 crores.

Even the Alia - Randeep Hooda starrer, Highway (2014) was made on a budget of ` 9 crore and it earned ` 30 crore.

Sajid Nadiadwala's upcoming film, Phantom, which features Saif Ali Khan and Katrina Kaif, is rumoured to have been made on a budget of ` 40 crore.

The prolific Director-Producer explains, "Last year, films like Highway, Heropanti or 2 States worked because they were cost-effective. So, the budget plays an important role in film-making today."

Smart budgeting is an important requisite for producing movies, feels Sajid. "Also, it's important to have a great team. I want to credit my team, as they worked on films like Highway, Heropanti and Phantom on one hand, and pulled off a biggie like Kick (2014) on the other," he says.

The Hit-Maker of film like 'Kick', says that the team of Phantom helped him plan the film's budget smartly. Sajid further adds "It has been done very intelligently, thanks to Kabir and my EPs . Although they filmed in around six countries, and about eight (international) cities, it was all intelligently planned. Everything worked out well,".

Sajid also credits the actors for helping him budget things smartly. He adds "I also want to credit the actors. People have realised that films like Phantom have different remuneration structures. I am glad that actors like Saif and Katrina, and even Kabir as a director, were really cooperative. And above all, having partners like Siddharth Roy Kapur and his team, gives us the courage to green-light a film like this (Phantom),".

Sajid's latest offering- 'Phantom' is all set to release on 28th August, 2015, which stars Saif Ali Khan and Katrina Kaif in lead roles.
