JK Rowling has hinted a new Harry Potter film is on the way, sending fans into meltdown.

The author of the hugely popular books took to Twitter yesterday to share a new picture of the Death Eater skull and Slytherin House snake.

Hinting a Cursed Child movie could be on the way, she wrote alongside the image: "Sometimes, darkness comes from unexpected places #HarryPotter #CursedChild."

The tweet was her first in six months, and fans took these two factors as a sign a film was being made based on Cursed Child, the wildly popular stage play that premiered in London three years ago and is currently playing in Melbourne and New York.

Tweeting below her post, one fan wrote: "Does this mean that there is going to be a #CursedChild movie trilogy with the original cast/trio reprising their roles? Please, can you share anything about #FantasticBeasts3?"

Another wrote: "WHAT DOES IT MEAN? OMG."

While a third speculated: "I'm extremely curious what this could mean. Does it have anything to do with the rumor (sic) of Warner Brothers wanting to buy the rights to Cursed Child?"

The Cursed Child is set 19 years after the end of the final Harry Potter movie, Harry Potter and the Deathly Hallows Part 2, and follows Harry, Ron and Hermione's children.

The first Harry Potter movie, Harry Potter and the Philosopher's Stone, was released in 2001 with Daniel Radcliffe in the titular role. Seven subsequent films followed, also starring Emma Watson and Rupert Grint. All Harry Potter movies are available to stream on Foxtel.

A spin-off prequel series of films are now being released on the big screen, starting with 2016's Fantastic Beasts and Where to Find Them starring Eddie Redmayne.
