Kapoor, who plays an Indian in the action film, praised his famous co-star, saying, "Tom Cruise is very dedicated and hardworking. Some days he slept for just three hours. That is the kind of drive and dedication which makes you so successful. It (Hollywood) is like a Premier League," he said.
'Mission Impossible 4: Ghost Protocol' is likely to hit theatres in December next year.
The 50-year-old actor, who starred in Oscar-winning movie 'Slumdog Millionaire' and went on to play the president of a fictitious Islamic country in US TV show '24', said, "Working at the international arena is altogether a different experience."
Talking about his journey as an actor so far, Kapoor said, "I had the opportunity of working with (British filmmaker) Danny Boyle. I learnt a lot from him. They have a different way of working and different work culture. In addition, I also had the opportunity of working with some of the great Indian directors and co-stars," he said.
"You should be like a blotting paper and absorb whatever is good. It has been a wonderful journey and God has been kind to me," he added.
Kapoor is currently focusing on his home production 'No Problem', a light-hearted comedy in which the actor himself stars as an inspector. Akshay Khanna and Sanjay Dutt play thieves while Paresh Rawal runs a bank. Suniel Shetty is a don in the film.
"We have tried our best to make 'No Problem' entertaining for every section in terms of its music, action, etc. I would say it's going to provide wholesome entertainment," said Kapoor.
"I think the most difficult thing is to make people laugh and that's precisely what this film is going to do," he added.
The Anees Bazmee directed film, which also stars Sushmita Sen and Kangna Ranaut, is set to release on December 10
