These kind of quotes often get blown out a proportion. I remember when, several years ago, a weary Anthony Hopkins, who had just come off a couple of exhausting shoots, made the mistake of mentioning to an interviewer that he was worn out and tired of making movies. Naturally, this led to a flurry of headlines about how Hopkins was retiring, quitting acting, and so on, when, really, he had just been expressing a desire to take some time off . . . .
Needless to say, Hopkins' "retirement" proved to be greatly exaggerated.
