Taken star Liam Neeson reveals that he originally didn't think his now iconic speech in the beginning of the film was very good. Taken, which was directed by Pierre Morel and co-written by Luc Besson, stars Neeson as ex-CIA officer Bryan Mills, who travels to Paris to save his daughter after she is kidnapped by Albanian sex traffickers. He discovers this has happened because she was on the phone with him at the time, allowing him the opportunity to speak to one of her captors and threaten that he will hunt the villain down using his "particular set of skills."
