The UK's Daily Mail reports that Harry Potter fan sites have received a lot of emails from parents.
"We as parents feel Daniel should not appear nude. Our nine-year-old son looks up to him as a role model. We are very disappointed and will avoid the future movies he makes," one parent wrote.
Another said: "I am curious as to how and why his parents said this was okay."
Some of his younger fans, however, are impressed with Radcliffe's tough new look.
"I am completely stunned by these pix," wrote Ginny Potter on fan site danradcliffe.co.uk.
