Pirates of the Caribbean stars Keira Knightley, Johnny Depp and Orlando Bloom are set to take part in a real-life adventure on the high seas.
The Hollywood trio will help to crew a boat taking part in the gruelling round-the-world Volvo Ocean Race.
The vessel will be named the Black Pearl - after the pirate ship in the film - and its sail will feature a giant skull and crossbones.
It is all part of a marketing stunt to promote the forthcoming release of the sequel Pirates of the Caribbean: Dead Man's Chest.
The stars will split the race between them - Knightley will join the boat while it is in Europe, Bloom will cover South Africa, Australia and New Zealand, and Depp will be on board when the yacht reaches the US and Brazil.
Each will undergo rigorous training at the race HQ in Portsmouth.
But while the rest of the crew will have to put up with the sort of living conditions yachtswoman Ellen MacArthur endured during her recent round-the-world voyage, the actors will be living in comparative luxury.
A special "Hollywood-style" berth is being built for them on the boat.
A spokesman said: "We will be laying on Egyptian cottons sheets, freshly cut flowers and special menus for each star."
The eight-month race covers 31,250 nautical miles and starts on November 12 in Galicia, northern Spain.
Knightley, 19, Depp, 41, and Bloom, 28, will take part in the inshore races at each of the main stopover ports.
The film is due for release in July next year and is a follow-up to the 2003 blockbuster which saw Depp Oscar-nominated for his role as Captain Jack Sparrow.
A third Pirates of the Caribbean film is planned for 2007.
