Zhang Yimou for more Hollywood-China collaborations

Zhang Yimou says the disappointing US performance of the biggest budget China-US coproduction to date, The Great Wall, may have been down to a weak story, but he hopes other filmmakers won't be put off from attempting such ambitious Hollywood-Chinese collaboration.

"The actors are all very good; (star) Matt Damon and everyone was splendid," said the acclaimed director on Tuesday.

"Probably the story is a bit weak, or the timing of it wasn't right, or we didn't do a very good job in making the film. There could be many reasons."
