"We haven't finalized on the leading lady yet. Amala Paul has been considered during our recent discussions, but we haven't approached her with the story yet. In about a week's time we should be able to finalise the heroine," Vetrimaaran told IANS.
Amala and Dhanush recently completed shooting for Tamil romantic-comedy Vela Illa Pattathari.
Meanwhile, Dhanush recently started shooting for his second Hindi project with filmmaker R Balakrishnan. The film also features megastar Amitabh Bachchan.
Amala is awaiting the release of her Tamil-Telugu bilingual Nimirnthu Nil.
