David Dhawan suddenly seems to have discovered a new formula for success. He is now into doing remakes of classic comedies. Even as he gets ready to do a remake of Sai Paranjpye's Chashme Buddoor, news comes that Dhawan would be doing his own take on Hrishikesh Mukherjee's 1975 comedy Chupke Chupke.

Apparently, David who has so far never worked with Abhishek Bachchan has offered the actor his father Amitabh Bachchan's role of the scatter-brained Botany professor from Chupke Chupke.

Writer-director Rumi Jaffery who has written any number of films for David Dhawan in the past has been given the job of writing the new version of Chupke Chupke.

Says Jaffery, "It's a big challenge for me. Hrishida's Chupke Chupke was written by Gulzar Saab. And now I've been given the task of writing the new adaptation of Chupke Chupke 36 years after Hrishida's film. How do I retain the flavour of the original and still make it palatable to contemporary tastes? Fortunately, after working with David on nearly 20 films we share a great comfort level. And we're both big fans of Hrishikesh Mukherjee."

Apparently, the original comedy on infidelity will be completely re-written, keeping in mind the act that the definition of infidelity has changed over the years.
