The two-disc director’s cut DVD of David Fincher’s Zodiac that’s being listed for sale on Amazon with a release date of January 8, 2008, touts a running time of 162 minutes, yet the awards screeners for the film — listed on the cover as being the director’s cut — come advertised with a 158-minute running time, which is the same length as the movie’s theatrical exhibition. So what gives? It’s a typo; the awards screener does indeed run 162 minutes, adding four minutes to the original cut. Still, that seems a pretty miniscule splitting of hairs for a dense, cerebral crime drama — who went to the mat for the studio over four minutes?
