Princess Diana will be the subject of a four-hour documentary miniseries airing on ABC this August.

A joint project of ABC and People magazine, the program, to be telecast over two nights, will include what the producers say will be in-depth conversations with those who knew her best, as well as archival footage of the Princess of Wales, mother of Prince William and Prince Harry.

The program will “remind the world why they fell in love with Diana in the first place,” according to Monday’s announcement.

The program will mark the 20th anniversary of Diana’s death at age 36 in a car crash in Paris on Aug. 31, 1997. She appeared on the cover of People 57 times, which is more than any other person in the magazine’s history.

Emmy winner Maura Mandt will be executive producer for the project, which will be produced for ABC by Time Inc. Productions. Time Inc. will also handle international distribution.
