'Karthik Calling Karthik' which stars the unusual pair of Farhan Akhtar and gorgeous Deepika Padukone in the lead also marks the debut of writer-director Vijay Lalwani.

Writing is Vijay Lalwani's first love and so perfect is he at that, that the script of 'Karthik Calling Karthik' was flawless, up until the climate forced him to alter a scene in the film. Yes you did read right, Vijay had to change just one part of the story due to weather!

Speaking on the re-written scene Vijay explains, "We shot the entire film as per the script, expect one scene which I had to re-write. The scene was when Farhan Akhtar was to propose Deepika Padukone; it was a very integral part of the film." Vijay continues, "I knew that I had to shoot that scene in a very grand way with loads of sunshine and it had to be an outdoor shot, but because it was June it was pouring...

So, we thought to shoot the scene in October, but when we started shooting, it rained on that particular day so at the last moment we decided to shelve the plan and go ahead with the proposal in rain, that's where I re-wrote the script."

Looks like Vijay has really drained himself while writing the script of 'Karthik Calling Karthik' (no pun). Going by the buzz for the movie it seems as a favorite among the youth who are eagerly awaiting its release on 26th February 2010.
