10 Movies That Must Return As A TV Series

8. Zodiac

David Fincher's 2007 cerebral crime thriller Zodiac tells the largely true story of a manhunt that started in the 60s and is still going on today. Lauded by critics for its unsettling atmosphere and faithful approach to real-life police work, the film follows the story as told by Robert Graysmith's 1986 non-fiction novel of the same name.

One criticism kept recurring, however, and it concerned how Fincher had attempted to cram in as much of certain elements as he could, whilst at the same time leaving out huge chunks of the investigation. An inevitable sacrifice one has to make to get a story of this size into a film, even if it still comes with a running time of 2 hours and 37 minutes, but not one you'd have to face when writing it as a television series. With the freedom TV would offer, the story could be better told across different timeframes.

Where Fincher's film largely focusses on the first few years of the case, before skipping through the late '70s and early '80s, the different eras of the case could form the basis for entire seasons of the show. It would also give someone the chance to actually address the major failing of the film - the total lack of context or explanation for why Graysmith becomes so obsessed with the case in the first place. Gyllenhaal does his best to portray the protagonist as a good guy who's doing what he thinks is right, but this falls someway short of making the break up of his marriage or 40+ year manhunt plausible.

Graysmith's as much a part of the Zodiac story as the killer himself, and a series would finally allow for some real exploration of him as a character.
