He is right-handed. (edit) William Petersen hosts a video shown at the Chicago Field Museum's DNA Discovery Center. The video, which explains the basics of genetics and DNA, is shown to vistors to the exhibit, which opened in April 2008. (edit) In 2007 William Petersen was reunited with director William Friedkin, when Friedkin directed an episode of CSI. Friedkin helped launch Petersen's career by giving him the lead in To Live and Die in L.A. in 1985. (edit) According to a 2007 TVGuide.com article, William Petersen's salary is $500,000 for each episode of CSI: Crime Scene Investigation. (edit) Billy has a dog named Bruno, who appeared with him on CSI's episodes Leapin' Lizards and Grissom's Divine Comedy. (edit)

William Petersen: (When asked if he thinks of quitting) And you have fans. You can't discout them. These people have made you. You have to be responsible to them, more than anything else, really. (edit) William Petersen: We were talking about how we're having friends now who are passing away. So you say, "What should I do with the rest of my life? Do I want to be the guy who was on CSI? What guy do I want to be?" (edit) William Petersen: (On Grissom's revelation of his romance with Sara) I'm not even sure that Grissom realized that he was saying it or that at the moment, he didn't realize that everybody was hearing it. It was a revelation on his part. And again more importantly that's really what has come to pass on this season is the realization on Grissom's part that...he loves someone. (edit) William Petersen: (On the CSI season 7 finale) The best way to put this is that, you know, i'm not a huge fan of cliffhangers endings. However I think because of what we've done with the whole minituare killer story line that in a way we've earned this ending, you know? It's not something that you can just wrap up quickly and walk away from it. (edit) William Petersen: (on stage fright) I had panic attacks during rehearsal. There were times when I really thought I wasn’t going to be able to do it. (edit)
