For Bad Boys Only is a 2000 Hong Kong science fiction action romantic comedy film directed by Raymond Yip and starring Ekin Cheng, Louis Koo, Shu Qi, Kristy Yang and Daniel Chan.

Recently, Taiwanese tycoon Yung Wing-hing (Ko I-chen) hires the agency to search for his ex-lover, Koon Ching (Shu Qi), whom was Asia's premier female air force pilot.

At the same time, a young man named Tin-ngai also hires the agency to search for his missing girlfriend, Shadow (Shu Qi).

Making matters more bizarre, King meets an amnesic girl named Eleven (Shu Qi), who also looks identical to Shadow and Koon Ching.

LoveHKFilm gave the film a negative review criticizing Manfred Wong's script as "overstuffed, underdeveloped, and embarrassing" and its "failed attempt" at charm and humor.
