Daniel Radcliffe has confessed that he finds it "scary" to appear naked on the London stage every night in Equus.

The Harry Potter star is currently playing Alan Strang, a stable boy who has a pathological fascination with horses, in the London production of Peter Shaffer's 1973 play.

He told Jonathan Ross: "I wasn’t so much intimidated by the part, even though I would be naked on stage and that was scary, but by the thought of going on stage and sustaining the energy for two-and-a-half hours."

Radcliffe's candid comments can be seen on Friday Night With Jonathan Ross, which airs tonight at 10.40pm on BBC1.
