The highly anticipated Princess Diana documentary, titled Diana, Our Mother: Her Life and Legacy, will air on Channel Seven's Sunday Night, at 7 p.m. The film is widely considered to be the most personal and in-depth of all the documentaries made about the princess so far — her sons, Princes William and Harry, and close friends like Sir Elton John all take part in it, providing never-before-heard stories and anecdotes.
In this preview clip above, Prince William talks about how he tries to keep his mum's spirit alive for his own children, Prince George and Princess Charlotte. "I think," he starts, "constantly talking about granny Diana." He adds that they have photos up all around the house, but the fact that his wife, Duchess Catherine, never met Diana makes it hard for her to contribute to their children's perception of her. "Obviously Catherine didn't know her, so she can't really provide that level of detail," he says. "I do regularly, putting George and Charlotte to bed, I do regularly talk about her and just try and remind them that there are two grandmothers, there were two grandmothers in their lives, and so it's important that they know who she was and that she existed."
