Arclight Films has acquired world rights to “Waiting Alone” (Du zi deng dai), the first feature by Chinese-American helmer Dayyan Eng (aka Wu Shixian), whose “Bus 44” was the first Chinese short to win at Venice and Sundance fests.

Urban comedy sports an ensemble cast of upcoming Chinese talent and a cameo by Hong Kong superstar Chow Yun-fat.

Tale focuses on an aspiring author who goes to absurd lengths to make a woman fall for him. Pic was voted best local film of the year by more than 50 Chinese newspapers.

The Australian-U.S. sales outfit negotiated the deal with Wu’s Beijing-based production shingle while en route to Hong Kong FilMart. Pic will be presented through Arclight’s recently established Asian label EastLight, headed by Ying Yi and Arclight co-prexy Gary Hamilton.

Taiwanese-born Wu is an American citizen who is part Chinese, part Scottish and part Persian.

He was the first foreign national to receive a best picture award at the Chinese Academy Awards last year and claims to be the only foreign helmer in the Film Directors Guild of China.
