'Skyfall': Daniel Craig slips back into blue trunks for James Bond 23

The photo, which was taken during filming at London's Four Seasons hotel, was revealed by Empire.

Craig famously emerged from the sea in his 007 debut Casino Royale wearing blue swim shorts. The scene was an homage to Ursula Andress's entrance in the first James Bond film Dr. No.

Skyfall, which opens in cinemas on October 26, also stars Judi Dench, Ralph Fiennes, Ben Whishaw, Bérénice Marlohe, Naomie Harris, Helen McCrory and Javier Bardem.

MGM and 20th Century Fox will release the entire James Bond series on Blu-ray boxset for the first time this year to celebrate the franchise's 50th anniversary.
