KEIRA KNIGHTLY is devastated upon concluding the final installment of Pirates Of The Caribbean movies, fearing she'll miss new "family" members Johnny Depp and Orlando Bloom. The 21-year-old actress, who plays ELIZABETH SWANN in the Gore Verbinski-directed trilogy, admits the cast became very close since shooting began back in 2002. The Love Actually beauty says, "I was very sad because we have all been through a lot together since the first one. "In a sense we've all become sort of a family so it's weird to think it's all over."
