MMA may sound like a food additive, but in fact it stands for 'mixed martial arts', a new kung-fu style adopted by action star Donnie Yen Chi-tan in his latest action film Flash Point. While the moves are impressive, if you are looking for a strong script and memorable characters, the movie is a let-down, especially given its director. Wilson Yip Wai-shun, best known for subtle relationship dramas such as Juliet in Love, has little room for character development in this story of two cops (played by Yen and Louis Koo Tin-lok) battling against three ruthless gang brothers. The incessant kung fu sequences, choreographed by Yen, are brutal yet spectacular. Some may find Yen's performance self-indulgent, but he has every right to show off, as he is the city's leading action star now Jet Li and Jackie Chan have left for Hollywood. Koo, whose acting improves with each film, offers comic relief, while mainland actress Fan Bingbing is a welcome break from the sweaty and bloody men. Flash Point is the third collaboration between Yip and Yen. Let's hope their next film has a human element. Flash Point is now available on DVD Correction Last week's movie ratings should have been four stars for Michael Clayton and two stars for Secret.
