And for anyone who’s too lazy here’s the info.

To promote Zodiac, Paramount posted on light-poles in major cities original sketches of the actual Zodiac killer with the words, "In theaters March 2nd," at the bottom.[23] The film was screened in competition at the 2007 Cannes Film Festival[24] on May 17, 2007 with Fincher and Gyllenhaal participating in a press conference afterwards.[25] The director’s cut of Zodiac was given a rare screening at the Walter Reade Theater in New York City on November 19, 2007 with Fincher being interviewed by film critic Kent Jones afterwards.[26]

Might be free. I don’t know if that’s still the case but I found this.
