London (Reuters): Britain's Prince William and his brother Harry recall memories from their childhood 20 years after the sudden death of their mother, Princess Diana , in a new television documentary to be broadcast this week.
The 90-minute film - "Diana, Our Mother: Her Life and Legacy" - celebrates the life and work of Diana, Kensington Palace said in a statement.
Diana, the first wife of heir to the throne Prince Charles, was killed in a car crash in Paris in August 1997 when William was aged 15 and Harry was 12. She was 36.
In the documentary, William - Queen Elizabeth's grandson and second in line to the throne - and Harry are filmed talking about their childhood as they look through photographs in a family album assembled by Diana.
Earlier this year, William spoke about how the shock of losing his mother still lingered two decades after her death . Harry said he had sought counselling to help deal with the grief.
A number of commemorative events have been planned to mark Diana's death .
William and Harry attended a private service earlier this month to re-dedicate her grave and the brothers have also commissioned a statue to be erected in her honor outside their official London home.
Rarely-seen possessions of Diana, including her music collection and ballet shoes, went on display on Saturday at Buckingham Palace.
An exhibition celebrating Diana's fashion opened in February.
