Kevin Costner and Ashton Kutcher visited a US Coast Guard station yesterday (28AUG06) to promote their new film The Guardian - and apologised for not being impressive. Faced by the real heroes, who regularly risk their own lives to rescue fishermen and boaters from dangerous ocean waters, Costner confessed he was more than a little humbled playing one of them. He said, "Actors are not nearly as impressive in person as we seem to be on film. "We get to portray these men and women, who are often tougher than we are, men and women who are often smarter than we are, and in the case of The Guardian, we are talking about men and women with the personal courage to put themselves in danger in a way I don't know I would." Costner and Kutcher will visit a string of US Coast Guard stations as part of their promotional tour for the film.
