The 23-year-old actor believes he is too old to return as the titular character if another 'Harry Potter' film was made, and if JK Rowling wrote another fantasy novel in the series he would only want a cameo as Harry's father, reported Contactmusic.
"Even if Jo did make another instalment, which is unlikely, I'd take a lot of talking round. I've done so much work to establish myself as something outside that series, I'd be really hesitant to go back.
The actor, who is currently starring in 'Kill Your Darlings', also said that he would love to land a supporting role in the next instalment of 'Star Wars'.
"Franchise mustn't become a dirty word. If directors like JJ Abrams and Joss Whedon keep doing what they're doing, it won't be. I'd love to be part of one again. Maybe not leading it, a nice supporting role. 'Star Wars' would be awesome. That'd be crazy cool," he said.
