Charles Brown Middleton (October 3, 1874 – April 22, 1949) was an American stage and film actor. During a film career that began at age 46 and lasted almost 30 years, he appeared in nearly 200 films as well as numerous plays. Sometimes credited as Charles B. Middleton, he is perhaps best remembered for his role as the villainous emperor Ming the Merciless in the three Flash Gordon serials made between 1936 and 1940.
