Chad Michael Murray: Halloween Horror Night!

Chad Michael Murray has a ghoulishly good time at Universal Studios Hollywood’s Halloween Horror Nights earlier in the week in Hollywood, Calif.

Tomorrow, the 30-year-old One Tree Hill actor will be at Barnes & Noble bookstore on the Upper East Side (86th & Lexington) for an “Everlast” book signing!

Other celebs who got in some screams and scares included Elijah Wood, Wilmer Valderrama (with Demi Lovato), and some cast members of this season’s Dancing With The Stars (David Arquette, Ricki Lake). Of course David posted with Scream‘s iconic “Ghostface Killer”!
