Daniel Radcliffe plays Harry Potter in the film series
The Harry Potter film set in Hertfordshire, where a stuntman was badly injured in an accident last month, has been allowed to reopen.
The Health and Safety Executive (HSE) cordoned off the area but has agreed it can be used again, a spokesman said.
David Holmes, from Leigh-on-Sea in Essex, a stunt double for star Daniel Radcliffe, remains in hospital with a serious back injury.
"We carried out a site visit and the set has now reopened," the HSE said.
It is understood Mr Holmes was practising an aerial sequence at the Leavesden Studios, near Watford, when he was injured on 28 January.
He is now receiving treatment at the Royal National Orthopaedic Hospital, in Stanmore, north-west London, which counts treatment for acute spinal injuries among its specialities.
A spokeswoman for the production team said filming on Harry Potter And The Deathly Hallows would begin later this month as planned.
"We have not begun filming yet and will not do so for another two weeks. This has always been the case," she said.
"Filming will commence mid-February and go through to spring 2009."
