Johnny Depp, Keira Knightley and Orlando Bloom are set to take part in a round-the-world yacht race. The 'Pirates of the Caribbean' stars will set sail on-board a replica of the film's Black Pearl ship - complete with a giant skull and crossbones sail - later this year to promote the movie sequel 'Dead Man's Chest' as part of the gruelling Volvo Ocean Race challenge. But the superstar trio will join the race at different legs of the journey to compete in one of seven in-port races rather than complete the full 30,000 mile global trip. Sexy Keira will board the boat when it docks in Europe, followed by Bloom, who will cover the South African leg and finally Depp, who will join the boat when it reaches south America. Walt Disney chairman Dick Cook said: "Given the film's high seas adventures and nautical themes, this marathon sporting event is a great way to make some waves and generate awareness among the millions of viewers." Over the next few months the trio will undergo rigorous training sessions at the race headquarters in Britain - before being treated to the relative luxury of the yacht complete with "Hollywood-style berths". A spokesman added: "We will be laying on Egyptian cottons sheets, freshly cut flowers and special menus for each star."
