Daniel Radcliffe is still seeking a way to distance himself from his old character. "I'm getting to a point where I feel like I made it out of 'Potter' OK and I'm really happy with where I am now, and to go back would be such a massive change to my life," he said in an interview with the New York Times. So perhaps after Radcliffe continues to establish his career, similar to how the cast of "Star Wars" did, he'd be ready to reprise his role as Harry. Or maybe not.
Either way, this is complicated by the fact that J.K. Rowling has yet to pen another title set in the wizarding world outside of the Hogwarts Library books, one of which already has a film series taking place before Harry's time. Instead, fans may see an adaptation of "Harry Potter and the Cursed Child," a play centering on Harry's youngest son, Albus Severus, and his friendship with Scorpius, Draco Malfoy's son. "Harry Potter and the Sorcerer's Stone" and "Harry Potter and the Chamber of Secrets" director Chris Columbus has expressed interest in that possibility (via Variety).
Time will tell, but there's no need to say "Avada Kedavra" on the idea of Daniel Radcliffe returning just yet; after all, Han Solo (Harrison Ford) picked up his blaster again!
