His film and TV career spanned from 1942 to 1977, and although mainly a character actor he is remembered for his part as Captain Greer in Disney's Bedknobs and Broomsticks (1971) and for his reoccurring role as Ravenswood the butler in The Beverley Hillbillies.

By the early 1930s Gould-Porter had moved to the United States and in 1931 he appeared at the Palm Beach Playhouse in A.A. Milne's Mr. Pim Passes By, to good reviews.

Gould-Porter continued to find work throughout the 1940s, appearing in minor parts in a string of Hollywood films, including roles in Jane Eyre (1943), National Velvet (1944) and A Double Life (1947).

Despite this larger role, it did not lead to greater success, but work continued to follow with an appearance in the Tony Curtis-led biopic Houdini (1953) and a part as the bartender in Abbott and Costello Meet Dr. Jekyll and Mr. Hyde (1953).

From 1955 Gould-Porter began appearing in more notable film roles, included credited parts in Lady Godiva of Coventry (1955) and Top Secret Affair (1957).
