Horns, the film where Daniel Radcliffe grows actual devil horns and starts hearing everyone's ugliest secrets, is streaming free on Tubi this September. No subscription. No free trial that quietly starts billing you next month. Just there.

The 2014 film catches Radcliffe two years clear of his last turn as Harry Potter, playing Ignatius "Ig" Perrish, a young man who becomes the prime suspect in his girlfriend's rape and murder before he starts sprouting horns that make everyone around him confess their darkest impulses. It's adapted from a Joe Hill novel, Hill being Stephen King's son, and directed by Alexandre Aja, the guy behind The Hills Have Eyes and, more recently, the shaky 2024 misfire Never Let Go with Halle Berry.

Critics weren't kind to Horns on release. It's mostly lived on since as a curiosity, the one where Radcliffe tried hardest to shake off the wand.

That curiosity is getting a fresh look now for a reason that has nothing to do with the film itself. HBO's upcoming Harry Potter series just dropped its first trailer, and it landed 277 million views in two days, organic numbers that broke an HBO record, according to Collider. Dominic McLaughlin steps into the round glasses this time, alongside Arabella Stanton as Hermione and Alastair Stout as Ron. Paapa Essiedu plays Snape, Janet McTeer is McGonagall, Nick Frost is Hagrid, John Lithgow is Dumbledore.

The casting has already stirred plenty of noise online, some of it about the actors, a lot of it about J.K. Rowling, whose name appears in bold on the trailer despite years of controversy trailing her. HBO doesn't seem to be flinching from that association.

None of that has much to do with Horns directly, except that Tubi's timing is obviously not an accident. If you want to see what Radcliffe did with his career right after he put the wand down for good, before Swiss Army Man, before playing Weird Al, before whatever comes next, this is the one. It also has a small early role for Sabrina Carpenter, years before she became one of the biggest names in pop, plus Juno Temple, Max Minghella and James Remar rounding out the cast.

Whether McLaughlin's Harry ends up anywhere near as strange or interesting a career as Radcliffe's is a question for much later. HBO hasn't set a premiere date for the series yet. For now, Horns is free, it's on Tubi, and it's still the strangest thing sitting on Radcliffe's post-Potter resume.
