Marta Balaga “Hard Boiled” director John Woo is developing a historical drama about Chinese American Dean Lung — the valet of Oakland’s first mayor Horace Walpole Carpentier — whose donation helped found Columbia University’s Department of East Asian Languages and Cultures. The film has the working title “Dean Lung.”The university still refers to the letter Lung sent to Columbia president Seth Low in 1901. “I send you here with a deposit check for $12,000 as a contribution to the fund for Chinese learning in your university,” it said.
