“Look what we made.” Anyone fighting back tears throughout The Theory of Everything let them run freely in the final scene, when Stephen Hawking types out these four words on his voice machine.

In the Oscar-winning film, the late, great scientist – who has died aged 76 – and his ex-wife Jane are watching their three children playing in the sunshine. Their 26-year marriage is over, but so too are any recriminations, and there’s a sense that the love, loyalty and mutual respect that remains is as much of an achievement as those three children.
