CANNES, May 19 — Hong Kong’s once world-famous movie industry wants to bring back the heydays of the 1970s to the 1990s by investing in a new generation of directors, the chairman of the city’s film development council told Reuters at the Cannes Film Festival.

“We should not forget our identity. How the people all over the world would look at us when they recognise a Hong Kong movie,” said Wilfred Wong, chairman of the council that is mainly responsible for government funding of the industry.
