Short answers, pulled from the story.
Alec Guinness de Cuffe entered the world at 155 Lauderdale Mansions South in Maida Vale, London, on the 2nd of April 1914. His birth certificate listed his mother as Agnes de Cuffe but left the father's name blank.
The identity of his biological father was never officially confirmed by any court or official record. Guinness himself eventually came to believe Andrew Geddes, a Scottish banker who died in 1928, was his father.
David Lean directed five major films featuring Alec Guinness over several decades. Their first collaboration occurred in Great Expections where Guinness played Herbert Pocket in 1946.
His final agreed-upon share stood at 2.25 percent of royalties paid to the director. The income from the films allowed him to live modestly without debts or financial pressure.
He died on the night of the 5th of August 2000 at King Edward VII's Hospital in Midhurst. He had been diagnosed with prostate cancer in February 2000 and liver cancer two days before his death.
