I went to see "Zodiac" today. It stars Jake Gyllenhall, Mark Rufalo, Anthony Edwards (with hair) and Robert Downey Jr. (amongst others). It's about the Zodiac killings that occured in San Francisco in the late 1960s, early 1970s (perhaps unsurprisingly) and sees Gyllenhall play a newspaper cartoonist who becomes obsessed with the case (Downey plays a reporter, and Rufalo and Edwards detectives).

It was a little long (it's more than 2hrs in length) and dragged in places, but it still does a good job of placing you in the time, telling you what happened, and showing what people were thinking as the murders took place (oh and with this being the 1960s and 70s, the haircuts are "Brilliant," as they say in the Guinness advert).
