Minghella, 54, died from complications following surgery for cancer of the tonsils and neck at London's Charing Cross Hospital in March (08).
The actors joined a diverse mix of guests - including former U.K. royal Sarah Ferguson, British prime minister Gordon Brown and his predecessor Tony Blair - to pay their respects to The English Patient filmmaker at the Thomas More Catholic Church, near Minghella's home in north London.
But the service, which followed a private family funeral, was not without its drama - singer/actress Jill Scott, who teamed up with Minghella for the TV movie The No.1 Ladies' Detective Agency, fainted during the service and had to be carried out by fellow mourners.
Paying tribute to his late friend, Law says, "He was a sweet, warm, bright and funny man who was interested in everything from football (soccer) to opera, and, most of all, his family."
