He found these duties dull, so auditioned for Squadron Leader Ralph Reader's RAF Gang Show entertainment troupe: Reader accepted him and Sellers toured the UK before the troupe was transferred to India.
In 1980 he won the Golden Globe Award for Best Actor – Motion Picture Musical or Comedy for his role in Being There, and was previously nominated three times in the same category.
Turner Classic Movies calls Sellers "one of the most accomplished comic actors of the late 20th century." In his personal life, Sellers struggled with depression and insecurities.
He first worked as a drummer and toured around England as a member of the Entertainments National Service Association (ENSA).
He developed his mimicry and improvisational skills during a spell in Ralph Reader's wartime Gang Show entertainment troupe, which toured Britain and the Far East.
