Daniel Radcliffe Vehicle 'Horns' Bedevils New Cast Members Juno Temple, Joe Anderson and Kelli Garner

nullJust the other day we were wondering when they were going to finish rounding out the cast for Alexandre Aja's adaptation of Joe Hill's wonderfully unsettling novel "Horns." Well, today seems to be that day, as The Wrap is reporting Juno Temple, Joe Anderson and Kelli Garner have now joined Daniel Radcliffe and Max Minghella in the cast. That's a spookily good line-up.

"Horns" concerns a young man (Radcliffe) who wakes up one morning with horns growing out of his forehead. These horns have certain powers, like being able to coax the truth out of people, which is helpful since he's taken to solving his girlfriend's gruesome rape and murder. Minghella was cast as Radcliffe's best friend, a lawyer who could be harboring dark secrets.

We assume that Joe Anderson, who made a splash as Peter Hook in the Joy Division biopic "Control" before having a fairly solid career as a second-fiddle character actor, appearing mostly in genre pieces like "The Ruins," "The Crazies," "The Grey," and this fall's "Twilight Saga: Breaking Dawn – Part 2," will be playing the older brother of Radcliffe's character.

As to who the girls play, we're not so sure. One of them will undoubtedly portray the slain girlfriend, who appears in the novel extensively in flashback/fantasy form. We assume there's another female character in the present storyline who our bedeviled lead interacts with (maybe Minghella's character's girlfriend), but we can't remember at this point (and we lent our copy of the book out to someone…). Temple has had a breakout summer, appearing in the huge smash "The Dark Knight Rises" as well as the much talked-about "Killer Joe," while Garner has been steadily working over the past few years, most recently in the ABC series "Pan Am."

"Horns" was adapted by Keith Bunin, a writer from HBO's shrink series "In Treatment," as a co-production between Red Granite Pictures and Mandalay Films, and the movie will be produced by Red Granite's Riza Aziz and Joey McFarland along with Mandalay's Cathy Schulman and Adam Stone. Hill and Red Granite's Joe Gatta will exec produce. Aja is the cracked French genius behind "High Tension," "Piranha 3D," and "The Hills Have Eyes" remake.

Production on "Horns" starts later this fall.
