Outside of Potter, he’s stripped himself of crutches to prove his standing.

Taciturn in 2007’s December Boys and self-mocking in Extras, Radcliffe silenced prurient fixations over the fact that he literally stripped off on stage as a disturbed hippophile in Equus with an impressively visceral performance.

Add his all-singing, all-dancing, all-year stint in Broadway’s How To Succeed In Business Without Really Trying – he recently finished his tenure, with the lead role taken up subsequently by Darren Criss, then Nick Jonas – and it looks like Radcliffe has been scaring himself into testing what he can do.

“A little bit,” he says. “I think stage is a place where I learn and get better. On a long run, you learn so much about your abilities.”
