VIDEO : Stephen Hawking's Kids Used to Make His Speech Synthesizer Say Swear Words

We didn't just learn more about everyone's favourite theoretical physicist Stephen Hawking in a new BBC documentary on Tuesday night, we also learned that his kids used to get creative with their dad's speech synthesizer. As part of his preparation, Redmayne says he spoke to Hawking's children Lucy and Tim. Eddie Redmayne shared the anecdote in Dara O Briain Meets Stephen Hawking while explaining how he prepared for his role as Hawking in Oscar-winning film The Theory of Everything.
Redmanye said,
"I spent a long time going to a motor neurone disease clinic and really trying to educate myself on the disease, and met many people who are suffering from it, and wanted to be absolutely authentic."
