STEVE Irwin's film crew secretly returned to the Queensland reef where he was killed to complete his final documentary, Ocean's Deadliest. Irwin's longtime manager and friend John Stainton revealed on US TV today that he had asked the crew on the morning after Irwin's death if they would like to complete the documentary. “To a man, they all said yes,” Stainton told CNN talkshow host, Larry King. Stainton said they secretly slipped out to Batt Reef on the Great Barrier Reef, where Irwin was killed by a stingray on Monday, to shoot the final scenes of the documentary.
