Daniel Radcliffe is set to make his first ever Comic-Con appearance this year to support his upcoming fantasy horror movie Horns. The actor will be joined by director Alexandre Aja and author Joe Hill for RADiUS-TWC's Hall H panel on Friday, July 25 from 3 PM to 4 PM, where the first trailer will debut.

Horns, which had its world premiere at the Toronto Film Festival last year, centers on a man named Ig Perrish (Daniel Radcliffe), who is mourning the sudden death of his girlfriend (Juno Temple). One morning, he wakes up and finds horns growing out of his head, which have the mysterious power to make anyone he is speaking to tell the truth. Heather Graham, Max Minghella, James Remar and David Morse co-star.

RADiUS-TWC's July 25 panel will also feature an appearance by Salma Hayek to promote her new action-thriller Everly, which was directed by Joe Lynch. The story centers on a woman (Salma Hayek) who must square off in her apartment with a horde of assassins sent by her ex-boyfriend mafia boss.

Daniel Radcliffe was scheduled to make his first Comic-Con appearance back in 2010, in support of Harry Potter and the Deathly Hallows - Part 1, which caused thousands of fans to camp out in front of Hall H. He was forced to cancel his appearance due to post-production work, although he did apologize to those devoted fans afterwards.
