The pictures have been released ahead of the opening of Equus, a
controversial Peter Shaffer play showing at London's Gielgud Theatre from
next month.
Radcliffe,17, plays a troubled stablehand who one night blinds six horses
with a hoofpick.
He features in numerous nude scenes with co-star Joanne Christie, the
woman in the publicity shots.
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.
