Either logo or name text. Either will do.

Zodiac Movie Logo  Sugerido por Usuario eliminado 605223 

I just posted a font that I made called Zodiac Movie Logo Font over on Fontspace.com This should help you with the font you are searching for.

And then some high quality fonts creators wonder how come their work is not accepted here at dafont ...

Enough! I am sick of your comments! I really have had it, koeiekat! I may not be a hotshot, but I certainly do not criticize anyone or tell them that they're blind, like you do. You never treat anybody right. So cut it out. I've seen the movie logo and that is what I based my font on. I have studied the Zodiac for a few years now, so you don't have the knowledge that I do of the Zodiac and I certainly am not giving you any information about the topic, koeiekat. If you were to actually look at the font I made you would see it is a near perfect replica of the font for the film itself!

Of course, if you don't want to use my font, that's okay too. But I found some links I think you should look at.
Here's the first one: http://blog.philstrahl.com/2007/08/31/zodiac-killer-font-part-1/
Here's number 2: http://blog.philstrahl.com/2007/09/01/zodiac-killer-font-part-2/
Here's the 3rd font: http://blog.philstrahl.com/2007/10/02/zodiac-killer-font-part-3/

These fonts were not developed by me. They were developed by a man named Phil Strahl.

I am merely sending you the links to each font.

Here are the names of the fonts as Phil has them on his site:

1: Zipher
2: Zanity
3: Zodiac
