Harry Potter, the HBO series, which is set to be released in 2027, is currently in production. The show's cast and crew include some very notable artists, like John Lithgow playing Albus Dumbledore, and Francesca Gardiner (known for being a co-executive producer on Killing Eve) joining as showrunner and writer.

HBO's "Harry Potter" television adaptation is slowly coming together, but we're still a ways out from actually getting it on our screens. That said, we are learning more and more as the months go on.
