The 26-year-old rose to stardom by playing the boy wizard in the Harry Potter films from 2001 to 2011.
However he has no plans to see how his character evolves as an adult in the top secret London stage show Harry Potter and the Cursed Child, because he worries his presence will prove distracting for the audience.
"It would be a weird one," Daniel told America's E! News. "I could be completely wrong in this, but I feel like if I went to see it that night, there's going to be a lot of Harry Potter fans there in the audience obviously and would that then become a thing?

After Harry Potter and the Cursed Child's preview shows, the two part play officially opens on 30 July (16), with its initial run at the Palace Theatre concluding on 27 May next year (17).
