I am only familiar with George Cole for one role and one role alone which made him a star and a legend, Arthur Daley in Minder.
Originally Cole was the support player to Dennis Waterman, playing an ex-boxer just out of prison, who the show was created for. But as the series grew Coles' Daley with his hair-brained money making schemes and illegal activities, plus his hillarious persona and disregard for other peoples feelings began to run the show.
Seldom can a mainstream character designed with so many flaws become so beloved but the way in which Cole became the character and created something special meant it was always going to be that way.
George Cole has had other roles on TV and Film but in the UK he will always be known as Arthur Daley, entrepreneur and husband of 'er indoors.moreless
