The director of the movie 'Onir' had been so obsessed with 'Raveena Tandon's' role in movie that he waited for 11 years for the actress to do the part. As initially Raveena could not do the movie due to her marriage and later on because of her being pregnant with children, but Onir was adament that whenever he'll make this movie it will have Raveena in it. So as a result the director had to wait for 11 years till finaly Raveena agreed to do the film
The Film was originally written keeping Raveena Tandon and Sunjay suri as leading pair in mind in 2001 after their critically acclaimed pairing in movie 'Daman'. After 16 years the Movie is being made with slight changes in script. Raveena and Sunjay are still part of movie but in different capacity this time. Sunjay is Producer of film and Raveena has an Important role as 'sonal modi' in film.
However it is the most awaited TV show but still Censor Board has banned it from airing because of it's 'Bold Content'.
Onir stated "The original title of "Shab" was "Kaash". It was the first script I wrote (2001) after I met Sanjay Suri and Raveena Tandon at the sets of Daman in 2000. Finally the film is now happening after 13 years.". Though the script was written for them, the lead cast of the film has been changed since it required a younger star cast. However, Onir is happy that Raveena and Sanjay are still doing the film. He added, "It is perhaps the destiny of the film that Raveena and Sanjay (though in different roles) are doing the film. Sanjay Suri does a cameo as her husband. The roles they were supposed to do are now being played by new comer Ashish Bisht and Bengali actress Arpita Chatterjee." Initially the role of Raveena Tandon was offered to Sangeeta Bijlani since this former actress was all set for her second innings in Bollywood. However, it seems that the dates did not work out and later, Raveena Tandon was approached for the same. Raveena Tandon will now play the role of a charming socialite in Shab.
The film did not have a theatrical release in British Columbia,Canada.
