20 Things You Didn't Know About Zodiac
10. Jennifer Aniston Was Instrumental In Casting Jake Gyllenhaal & Mark Ruffalo
Jennifer Aniston is probably the last actress you'd expect to have any involvement with a movie as grim as Zodiac, but she actually played a major part in ensuring the casting of both Jake Gyllenhaal and Mark Ruffalo.
During pre-production, Fincher met up with Aniston and asked her who some of her favourite co-stars were, and she answered with Gyllenhaal - who she starred with in 2002's The Good Girl - and Ruffalo - who she teamed with on 2005's Rumor Has It.
Fincher is such a singular, meticulous filmmaker that it's tough to imagine him ever having such a conversation, especially with Jennifer Aniston of all the people in Hollywood.
