Bollywood heartthrob Hrithik Roshan, who will be seen with Aishwarya Rai Bachchan in Sanjay Leela Bhansali's upcoming film "Guzaarish", feels that he shares a perfect equation with the actress.

"Our equation has been perfect. We both share the same amount of passion for films and our approach to our work is similar. We are selfless and enjoy teamwork. I remember the first shot I gave with Aishwarya 10 years ago for an ad, and till this time we have been able to sustain our equation, " Hrithik, who was present at DT Cinemas in south Delhi's Saket area to promote the film, told reporters Tuesday.

Hrithik and Aishwarya have previously been paired together in Yash Raj's "Dhoom 2" and Ashutosh Gowariker's "Jodhaa Akbar". Both the films raked in moolah at the box-office and the pair wowed the audience with their sizzling chemistry.

"There were times when I used to show Aishwarya the shots I had given. Many times it happened that she used to walk out without giving any reaction and I used say to myself, 'I have to do the shot again', " said the 36-year-old actor, who was spiritedly promoting the film despite being down with fever.

"That level of communication and honesty comes only when you are friends and there are no ego hassels, " he added.

Hrithik was also full of praise for Bhansali, with whom he worked for the first time in the film.

"While working with Bhansali, the kind of creative freedom I have enjoyed as an actor, I have never enjoyed in my life. He just let me fly. There were times when we used to come on sets and I used to have some thoughts in mind to add to the scene. But we used to communicate at such a level that we never sat and discussed it together, " Hrithik said.

"It used to automatically come out in the shot. And this is possible only when there is a lot of faith on both sides, " he added.

"Guzaarish", a story about a magician who becomes quadriplegic when one of his tricks goes wrong, will hit screens Friday.
