Hong Kong and Los Angeles-based sales agent The Film Library has picked up international rights to US$10m Hong Kong animation Dragon Blade and Green Tea directed by mainland Chinese director Zhang Yuan.

Dragon Blade, directed by Australian stunt co-ordinator Antony Szeto, is the first feature-length 3D computer-animated film to be developed and produced in Hong Kong. Billed as 'Shrek meets Crouching Tiger, Hidden Dragon' the film is produced by Hong Kong animation studio DCDC Productions which has previously produced TV series Butt Ugly Martians.

Martial arts master Wu Bin, whose former students include Jet Li, is working as a consultant on the film. Hong Kong stars Daniel Wu and Karen Mok are providing the English-language narration. Chinese and other foreign-language versions are also planned.

Zhang's Green Tea, which was shot by Hong Kong-based cinematographer Chris Doyle, is the story of a man who believes he is in love with two different women - only to discover they're the same person.

The cast includes Jiang Wen, one of the jury members at this year's Cannes, and rising mainland star Vicky Zhao. The film was produced by China's Asian Union Film, headed by Dong Ping, which was one of the co-producers behind Crouching Tiger.

Zhang's credits include Seventeen Years which won the best director award at the Venice Film Festival in 1999.
