Hollywood loves to stretch movie franchises for as long as possible, so it's no surprise that a Harry Potter and the Cursed Child adaptation is already rumored to be in the works.
According to sources in the New York Daily News, Warner Bros. is eyeing the possibility of turning the play into a trilogy. Since the theatrical version of The Cursed Child clocks in at about five hours, there's certainly enough material to go around.
The Daily News also reports that Warner Bros. wants Daniel Radcliffe to return as Harry Potter, although we're taking that rumor with a hefty pinch of salt. Radcliffe has a flourishing career in smaller indie movies and has shown no measurable interest in reprising his former character in any form. He's also said several times that while he looks back on the Harry Potter movies with fondness, he's done being Harry Potter.
Fantastic Beasts and Where to Find Them is set to become a trilogy, with the third instalment due out in 2020. This leaves plenty of time to write and cast a Cursed Child adaptation, meaning Warner Bros. has the option of raking in more cash from Harry Potter films for the next decade or so. The studio already filed for a trademark on The Cursed Child back in July, so while nothing has been officially confirmed, a screen adaptation seems very likely.
