Roger Moore

Father of the woman in the 'Scottish Widows' adverts on television, and sometime UNICEF ambassador.
Most famous for his appearances in many of the best films in the James Bond series (Live and Let Die, The Man With The Golden Gun, The Spy Who Loved Me) although arguably only the second best actor to play the role.
The fact that his part in Cannonball Run is not more widely appreciated or celebrated can only be described as a travesty of justice.
