: You cannot learn anything from success, you only learn from failure.
Jim Dale began his career as a stand-up comic. He sharpened his comedy skills during a stint in the army, where he organized and performed in camp shows.
After his discharge he pursued a comedy career, and landed a job as the warm-up comic on a musical variety show. He did so well that the producers gave him a spot on the show as a singer, and he quickly became a recording star.
He was signed for a small part in one of the "Carry On" films, Carry On Cabby, but the audience reaction to him was so great the he was soon made a regular member of the cast.
Unlike many comics, Dale insisted on performing his own stunts, and in fact injured his arm performing a stunt in Carry On Again Doctor, his last film of the series until 1992.
He performs the unabridged Harry Potter audio books and is cited twice in the Guinness Book of World Records for creating the most character voices in an audiobook (more than 200)
