Stephen Hawking's ex-wife has told how the physicist's fame damaged their relationship.
The couple were married for 30 years from 1965 after they met while studying at Cambridge.
New movie The Theory Of Everything, which stars Eddie Redmayne and is being tipped for Oscar glory, is based on Hawking's first wife Jane Wilde's memoir.
Ms Wilde, who is played by Felicity Jones, said "life became very complicated" after the publication of A Brief History Of Time in 1988.
"I rather felt that the family had been left behind. To me, Stephen was my husband and the father of my children; one does not say to one's husband 'Oh, you're so clever! I must worship the ground under your feet, or, in this case, wheels'," she said.
