He appeared in several stage productions, and made his television debut in 1956. He then went on to sign a movie contract with FOX in the late 1950's, which led him to a string of film roles.
Sean Connery is most likely to be remembered as 'James Bond' to those who cannot remember his name. He was cast as James Bond in 'Dr. No' in 1962 over many other accomplished actors, even though Ian Fleming, the creator of James Bond 007, was quoted as saying, "He (Sean Connery) is not exactly what I envisioned" as the fictional British agent. Nevertheless, the film was a success, and led to 3 more Bond films in the next 5 years. Recent popularity polls stated Connery as the 'Best Bond', a win over Roger Moore, George Lazenby and company.
Tired of being type-cast as as 007, Connery quit the role after 'You Only Live Twice', in order to 'devote more time to his family and to golf'. The next Bond film was made with George Lazenby, but Connery was persuaded to return as Bond in 'Diamonds are Forever'. With that role, he said he was finished as Bond, but he returned for a final appearance mostly because of the money offered in 'Never Say Never Again'.
Connery has played many varied roles in films over the years, working with directors such as Hitchcock, Huston and De Palma. He won the Academy Award for Best Supporting Actor in 1987, for his role in 'The Untouchables'. He has been quite subdued since, occasionally appearing in movies these days, like 'The Rock'. He is still working in the scene today.
