Actor Daniel Radcliffe, who plays the bespectacled boy wizard in Harry Potter, says the new film in the franchise will make some people uncomfortable.

The 21-year-old actor, who has finished filming the final two movies in the blockbuster franchise, says his character will be very close to death after being beaten up by his arch-nemesis Voldemort, which will be difficult for some fans to watch, the Contactmusic reported.

"Voldemort does absolutely kick six bells out of me, and that's what makes it effective, the fact that Harry's a kid having the crap beaten out of him. If it's Voldemort killing an adult - well, he does that loads in the films," Radcliffe said.

"To see him brutalising and desperately trying to kill a 17-year-old boy is hopefully going to shake some people up," he added.

The actor, who was only 11-year-old during his first Harry Potter film, believes that the his character is yet to grow up.

"Someone said to me the other day, 'Is there one point where Harry becomes a man?' and the thing is, I don't think he does in this film, because the point is he's still 17," Radcliffe said.
