While it's sad Cannes didn't award David Fincher's "Zodiac" with the jury's grand-prize for Best Director, the french are sure trying to make it up to us: Here's a great video from a Cannes press conference with Zodiac's amazing cast -- Gyllenhaal, Sevigny and Ruffalo.
If you don't happen to be fluent in french you may have a hard time figuring out the questions. However the answers are in English.
And easily understandable.
A second TV-excerpt I found has Jake Gyllenhaal visiting The Daily Show. It's not exactly informative -- but should help to shorten our wait for the DVD-release!
