The Duke of Edinburgh will be joined by 007 stars including Sir Roger Moore, Dame Judi Dench and Naomie Harris for a James Bond-themed charity gala.
Thursday's Diamonds Are Forever fundraising event will mark the 60th anniversary of The Duke of Edinburgh's (DofE) Awards.
Hosted by David Walliams, it will be attended by past and present cast and crew from the spy film series, including producers Michael Wilson and Barbara Broccoli.
British film composer David Arnold, who scored five of the Bond films, will organise the entertainment programme. The evening event will be held at Stoke Park in Buckinghamshire, which featured in Goldfinger and Tomorrow Never Dies.
Prince Philip, who founded the charity in 1956, will be attending along with The Earl and Countess of Wessex.
The DofE Award is the world's leading youth achievement award and the scheme works with more than 300,000 young people in the UK each year. All proceeds from the gala will go towards helping the charity, which aims to engage with two million more young people by 2020.
It also operates in more than 140 countries and territories.
