Actor-filmmaker Kamal Haasan says his Hollywood dream will take some time to come true as he is currently busy wrapping up his Tamil action-thriller "Vishwaroopam".

"I've poured all my energy and focus into 'Vishwaroopam' now. I can't think of Hollywood project until my current one is complete.

Although I have put the idea for the English project together, but I believe it still needs some fine tuning, " Kamal told reporters Wednesday on the occasion of his 58th birthday.

Hollywood producer Barrie Osborne, Known for films such as "Face Off" and "The Matrix", is keen to work with Kamal.

"Vishwaroopam", written and directed by Kamal, stars Rahul Bose, Andrea Jeremiah, Pooja Kumar and Jaideep Ahlawat in the lead roles. It will release in Hindi as "Vishwaroop".

Meanwhile, the film's audio, which was earlier scheduled to be launched Nov 7, in three different cities, has been pushed to an undisclosed date due to weather conditions.
