Takuya Kimura ("2046"), Lee Byung-hun ("A Bittersweet Life") and Shawn Yue Man-lok ("Infernal Affairs") have joined the cast of Josh Hartnett psychothriller "I Come With the Rain" reports Variety.

Director Tran Anh Hung's English-language $18 million pic concerns a private detective (Hartnett) hired by a high-ranking businessman to search for his missing son in the Far East.

High-def shooting in Hong Kong began two weeks ago and is due to wrap in early October. Summer rainstorms and typhoons have complicated matters.

A week-long shoot in the Philippines is already done, and production will return to Hollywood after the Hong Kong stint to wrap filming in November.
