Daniel Radcliffe has described his role in Horns as the most "emotionally intense" character he's ever played.
Based on the novel by Joe Hill, Horns revolves around a man named Ig who is suspected of murdering his girlfriend.
He then wakes up one day to discover that he has grown a pair of horns and acquired powers that might allow him to discover the identity of the real killer.
Radcliffe told Total Film that his character is a "good person", but more angry than other roles he has played in the past.
"He's a good person who has something inexplicable and terrifying happen to him," Radcliffe explained.
"Ig's anger is a lot more on display than any character I've played. The way he lashes out at the world is much more overt than I've done before.
"And I think, frankly, it's one of the most emotionally intense characters I've ever played."
Horns is due for release on October 31.
