LOVE AAJ KAL seems to be "inspired" , as we know  what  that means,  from a  Taiwenese film, HAO DE SHI GUANG (Three Times).

In THREE TIMES  - The movie starts in 1911 then moves to 1966 and eventually culminates in 2005.

The story of THREE TIMES runs in three phases. It features three chronologically separate stories of love between the two protagonists, in the first two stories, letters are crucial to the outcome; in the third, it is cell phone calls, text messages, and a computer file.

Over the years between the tales, as sexual intimacy becomes more likely and words more free, communication recedes.

 Imtiaz Ali directed LOVE AAJ KAL starring Saif Ali Khan, Deepika Padukone and Florence Brudenell Bruce is all about how love was perceived back in the olden days compared to how it is in modern times.

The story has Saif in  turban romancing Florence in the second part in the film where love is all about innocence. The third part has Saif and Deepika playing non-committal lovers just there for fun, sex & short romance without marriage.

But Imtiaz however denies the resemblance by stating there are just two stories portraying love then and now. The USP or the main attraction of the film is the love story between Neetu & Rishi Kapoor which is the first of the three love stories which is different.

To know the real truth behind this rumour we would have to wait for 31st july.
