The publicity shots were taken between filming of the fifth and sixth Harry Potter movies.

The play's producer, David Pugh, told the Daily Mail that Radcliffe had been rehearsing the nude scenes with Christie for more than a week and had overcome his initial shyness.

The young actor's spokeswoman, Vanessa Davies, said: "Daniel does not want to step away from Harry Potter but he does want to show he is a rounded actor capable of very different and diverse roles."

"He has tremendous support from Harry Potter fans," she said.
