Zodiac

In Zodiac, director David Fincher (Seven) tackles the true tale of still-unsolved serial killings from the perspectives of three men obsessed with the case: a San Francisco newspaper cartoonist (Jake Gyllenhaal), a crime reporter (Robert Downey Jr.), and a detective (Mark Ruffalo). Tremendously ambitious, the movie, which captures its ’70s era vividly, also has a flat, abrupt ending. The DVD cries out for a commentary; we’ll get it — plus other bonus features — in a Director’s Cut slated for 2008. Well worth seeing, but save some dough for next year. EXTRAS None. B+
