Princes William and Harry both serve in the Armed Forces
Princes William and Harry will attend the world premiere of the next James Bond film, Quantum of Solace.
They will be joined on the red carpet in London by 007 actor Daniel Craig, as well as co-stars including Dame Judi Dench and Gemma Arterton.
The Royal brothers have asked for proceeds from the event to benefit two charities - Help for Heroes and the Royal British Legion.
The premiere will take place on 29 October in Leicester Square.
The film's producers, Michael G Wilson and Barbara Broccoli, said: "We are pleased this event will help raise much needed funds to support the servicemen of our country through the princes' chosen charities."
Since its launch last October, Help for Heroes has raised £6m for wounded servicemen and women.
The new film will open with a car chase in the streets of Siena, Italy
The Royal British Legion provides support for those who are currently serving, or have served, in the Armed Forces and their families.
Quantum of Solace, the 22nd official film in the 007 series, picks up from Casino Royale as the secret agent sets out to avenge the apparent death of his lover.
It has a bigger budget than Casino Royale and producers have promised more action.
The title is taken from a short story published by Bond creator Ian Fleming in 1960.
It will hit cinemas on 31 October in the UK, with the rest of the world seeing it from early November.
