He's directed some of the most critically acclaimed, visually arresting movies of our time and has been celebrated by his colleagues, but this morning Christopher Nolan's name was a notable snub on the list of Best Director Oscar nominees.

Nolan -- a three-time Directors Guild of America nominee for 'Memento,' 'The Dark Knight' and 'Inception' -- has yet to be recognized in the director category by the Academy. Sure, his movies often score nominations galore; 'Inception,' for example, is up for eight awards this year, including Best Picture and Best Original Screenplay. But for some reason, the Academy continues to ignore him as a directing contender.

Could it be because his inventive movies are typically also enormous blockbusters? Doubtful. Enormous box-office success didn't prevent Steven Spielberg from joining the nominees' circle early in his career (for 'Close Encounters of the Third Kind,' 'Raiders of the Lost Ark' and 'E.T. the Extra-Terrestrial,' popcorn flicks all). And it certainly hasn't hurt two-time-winner James Cameron.
