AceShowbiz - The "Harry Potter" universe, known for its quintessentially British flair, might soon see an American actor don the robes of one of its most beloved characters. According to multiple reports, six-time Emmy-winning actor John Lithgow is nearing a deal to portray Professor Albus Dumbledore in HBO's much-anticipated "Harry Potter" series reboot.

Currently in pre-production, HBO has been tight-lipped about the casting process, only promising to confirm details when deals are finalized.

"We appreciate that such a high-profile series will draw a lot of rumor and speculation," HBO commented. "As we make our way through pre-production, we will only confirm details as we finalize deals."

Author J.K. Rowling has reportedly been involved in the casting process, ensuring a faithful adaptation of her novels.

John Lithgow, although American, brings notable experience in portraying British characters. He earned an Emmy Award for his portrayal of Winston Churchill in "The Crown" and recently wrapped up a stint playing Roald Dahl in the West End play "Giant."

These roles have showcased his ability to authentically capture British personas, making him a strong contender for the role of Hogwarts' esteemed headmaster.

Throughout the Harry Potter film franchise, Albus Dumbledore was portrayed by Richard Harris and later Michael Gambon, with Jude Law stepping into the role for the "Fantastic Beasts" prequel movie series.

HBO's Harry Potter reboot is led by writer and showrunner Francesca Gardiner along with director and executive producer Mark Mylod lead the project. Filming is set to take place at Warner Bros Studios in Leavesden, with a slated debut sometime in late 2026 or early 2027.

The new series promises to delve deeply into the beloved novels, an endeavor that has garnered significant interest and speculation regarding casting choices. Reports have suggested Paapa Essiedu for Professor Snape while other actors like Sharon Horgan, Lesley Manville, Brett Goldstein, and Cillian Murphy have been rumored for various roles.

As fans keenly await official announcements, the idea of a renowned American actor stepping into the role of Albus Dumbledore may very well redefine the character for a new generation of viewers. For now, the magical world of Hogwarts stands at the cusp of a new era under the wand of John Lithgow.
