Just last month, Warner Bros. filed for a trademark on Harry Potter and the Cursed Child, the hit stage play (the script was also released in book form) that serves as the eighth installment in J.K. Rowling’s classic series. While that doesn’t necessarily indicate that WB is plotting a new Harry Potter movie, a new rumor suggests that that’s exactly what it means — and they want Daniel Radcliffe to return for not just one, but three films.
