Actor Eddie Redmayne visited a motor neurone clinic in London to help him prepare for his latest movie role.
The 32-year-old plays theoretical physicist Stephen Hawking, who suffers from the disorder, in the Theory of Everything.
He said playing the role was difficult but he had four months to prepare.
“If you’re lucky enough to play someone like Stephen Hawking you feel quite a gigantic sense of responsibility,” he told London Live.
The Hollywood actor has now returned to London and added he is looking forward to eating cheese and marmite paninis and visiting Borough Market.
