Lucy Hawking, creator of the George Greenby books and daughter of physicist Stephen Hawking, says she has dreams where her father is able-bodied and can walk.

She said the film 'The Theory of Everything', in which Eddie Redmayne portrays her father, allowed her to see him as a young man and imagine him without his wheelchair.

"I'd never seen my father walk and that for me is the most really affecting moment", she said.
