Kristopher Kum
From Tardis Wiki, the free Doctor Who reference
Kristopher Kum (born 23 June 1929) played Fu Peng in the Doctor Who story The Mind of Evil.
He was not the original actor cast for Fu Peng, but stepped in after a disastrous location shoot. Just prior to the studio recording, director Timothy Combe came to Kum — then the head of Oriental Casting, a talent agency for actors of Southeast Asian descent — and Kum put himself forward. However, in a way not detectable to Combe — or most audience members — he was partially inappropriate for the role, since the part required a Hokkien speaker and he natively spoke Cantonese.
