Journalist and writer turned television personality. Had a very bad
stutter which became his trademark.
His father was James Henry Mussen Campbell, a lawyer who was Ireland's
Solicitor General, Attorney General, Lord Chief Justice, and Lord
Chancellor before becoming the first chairman of the Senate of the
Irish Free State.
In his autobiography (and several interviews), he claimed he "could never quite get the hang of writing scripts"; nonetheless, he wrote ten films and a great deal of television (often in collaboration with his third wife, Vivienne Knight).
