The director of Kangna Ranaut-starrer film, Sai Kabir's first directorial venture 'Chemistry' is yet to release

Writer-director Sai Kabir's Kangna Ranaut-starrer, 'Revolver Rani', hits the marquee tomorrow, but his directorial debut, 'Chemistry', has not yet seen light of day. Starring Shreyas Talpade, Soha Ali Khan and Tanishaa Mukerji, the film was shot almost four years ago.

Says a source, `The film, though complete, did not see light of day due to production issues. There were differences between the producers. Shreyas, who was also co-producer, tried to help the film get a release, but it was of no use.`

Sai has earlier penned films such as 'Lamhaa' (2010) and 'Kismet Konnection' (2008). 'Chemistry', a romantic comedy, deals with the love equation between a highly ambitious girl and a boy-next-door who has a penchant for kulfis.

Interestingly, it was Shreyas's bonding with co-actor Kunal Khemu on the sets of 'Golmaal 3' that translated into a role in 'Chemistry' for the latter's flame, Soha Ali Khan.

During the France schedule of the film, Tanishaa's make-up and hair was done by professionals in Paris as Sai wanted her look to be along the lines of socialite Paris Hilton.

Sai remained unavailable for comment.
