ET caught up with the 25-year-old actor at Comic Con 2015 in San Diego, California, and while he's excited for J.K. Rowling's latest Potter-world project, it's not looking like Harry Potter will be showing up in the prequel.
"I still get people saying, 'Are there going to be any more movies?' And now I can say, 'There are actually are,'" Radcliffe admitted to ET, adding, "But I'm not going to be in them."
Fantastic Beasts is about the adventures of writer Newt Scamander (Eddie Redmayne) in New York's secret community of witches and wizards, 70 years before Harry Potter reads his book in school.
Radcliffe says some of his fans pity him after hearing he won't be appearing in the movie. "And they're like, 'Oh sorry,' and I'm like, 'They're set in the past. Don't worry about it!'"
He quipped that being in all eight of the original Harry Potter films was enough for him. "Yeah, eight was cool," he told ET.
While he may not end up in the highly anticipated Fantastic Beasts, Radcliffe did disclose that the film -- set to hit theaters in 2016 -- will probably start filming "soon."
Radcliffe also isn't above talking all about Harry Potter, even though the final film premiered back in 2011. "I would be crazy if I minded talking about it," he said.
Radcliffe was at Comic-Con promoting his upcoming movie Victor Frankenstein alongside his co-star James McAvoy. The horror movie hits theaters Nov. 25.
