While working as a reporter for the Tampa Tribune, he was spotted by director Henry King, who was in Florida to make Hell Harbor (1930). King hired Hatton for a bit part, and Hatton eventually moved to Hollywood, where he appeared in a series of small roles, most notably as a contestant in an “ugly man competition” in The Hunchback of Notre Dame (1939) and as a member of the lynch mob in The Ox-Bow Incident (1943). He first appeared as a character called “The Creeper” in the Sherlock Holmes thriller The Pearl of Death (1944), and then twice more in two horror films that were unrelated to the Sherlock Holmes series, House of Horrors and The Brute Man, both of which were directed by Jean Yarbrough.
