Chow Yun-fat is attached to star in gambling-themed action drama Bluffing, which is being produced by Wong Jing’s Hong Kong-based Mega-Vision Project Workshop.

Written and to be directed by prolific Hong Kong filmmaker Wong Jing, the film will star Chow as a former conman who is invited by Hong Kong police to go undercover to investigate a money laundering case in Macau. Nicholas Tse is also being lined up to star.

Mega-Vision is aiming to start shooting the film in December 2012 or January 2013. Production will take place in Hong Kong, China and Macau. China’s Bona Film Group (BFG) is also likely to board the production. Wong Jing recently directed The Last Tycoon, starring Chow, for BFG.
