SRK has made it amply clear that his upcoming home production 'Om Shanti Om' is not a spoof on Hindi cinema of the 70s.

Addressing the media here yesterday, after releasing the film's music, SRK said he feels the biggest USP of the movie was that it seriously recreates the era of 1970s and it was his achievement as a producer.

'' The film is about reincarnation. The Om of 70s is Om Prakash Makhija, a struggling actor trying to make it big while the Om of 2007 is Om Kapoor, a superstar who is not talented,'' he said.

On his expectations from the film, he said, ''you cannot satisfy all people at all times. I am releasing the movie on Diwali. The film is about celebration of life and happiness. Besides, there is lot of comedy and drama.

Director Farah Khan has got a good ear for music unlike me. There is variety in the music of this film.'' Speaking about the other Bollywood biggie 'Saawariya' which releases on the same day as 'Om Shanti Om', Shah Rukh said 'Saawariya' was a huge movie as compared to his own.

''Mine is a secondary film compared to Saawariya. It could have been good for business if the release dates had not clashed. But, there is no competition. There are enough people to see both films,''he said.

''Sanjay Leela Bhansali has given me 'Devdas' which I consider as a the highlight of my career. Besides, Rani and Salman who are in Saawariya, I have lot of love for debutants Ranbir and Sonam who respect me tremendously. Hence, I pray for both the movies. But, after all Om Shanti Om is my child,'' he added.

''I am grateful to everybody including Dharmendra, Shabana Azmi, Mithun Chakravarty and all other friends from the industry who agreed to be part of the film.''

Shah Rukh said he went on a diet control for four months and also worked out. ''I am feeling good and healthy. Salman Khan and Hrithik Roshan were very co-operative. Infact, I showed them my pictures before commencing shooting.

They said I was good and needed to improve further.'' He spoke highly of his debutant co-star Deepika Padukone.

''we feel a huge responsibility towards her. She has all the makings of a good star-actress,'' he added.
