At the first read-through, Depp surprised the cast and crew by portraying the character in an off-kilter manner. He researched 18th-century pirates and, seeing parallels with modern rock stars, modeled his performance on Keith Richards. Richards later appeared in two cameos as Jack's father, Captain Teague, in "At World's End" and "On Stranger Tides". Verbinski and Bruckheimer had confidence in Depp, partly because Orlando Bloom would play the traditional Errol Flynn-type character. Depp improvised the film's final line, "Now, bring me that horizon", which the writer called his favorite line. Disney executives were initially confused by Depp's performance, questioning whether the character was drunk or gay. While watching the rushes, Disney CEO Michael Eisner proclaimed Depp was ruining the film. Depp's response to Disney executives was they could trust him with his choices or let him go. Many industry insiders questioned Depp's casting, as he was an unconventional actor not known for working within the traditional studio system.
