Daniel Radcliffe is attending Comic-Con for the first time in conjunction with Horns, the Radius-TWC fantasy horror release that he is toplining. Radcliffe will appear alongside Horns director Alexandre Aja and novelist Joe Hill in Hall H from 3-4PM Friday, July 25, to show off the trailer for the film, which follows “Ig” Perrish, a young man who sprouts horns following his girlfriend’s (Juno Temple) murder. Ig’s horns have the power to put people in a trance and trigger them to speak unspeakable thoughts. Horns premiered at the Toronto International Film Festival last year. In 2010, eager Harry Potter fans clad in Hogwarts robes waited hours to see him at Comic-Con’s Harry Potter And The Deathly Hallows panel, but Radcliffe was a no-show due to postproduction work, later apologizing to the franchise’s devotees. In addition, Salma Hayek will be showing brand-new footage from Radius-TWC’s action-thriller Everly directed by Joe Lynch. Hayek plays a woman who faces down assassins sent by her ex, a mob moss, while being stuck in her apartment.
