Bitter Chocolate, an upcoming film written and directed by Kamal Haasan, was expected to feature him and his elder daughter Shruti Haasan in off-beat characters. But, the actress has opted out of the project due to lack of convenient dates. “I'm not a part of Bitter Chocolate with my father. I'm both sad and happy to say I have no dates at the moment… Next time,”, she posted on her social networking page. Bitter Chocolate is expected to go on floors after Kamal Haasan completes his Vishwaroopam sequel, say reports.
