It’s Oscars night and the smart money’s on Eddie Redmayne as Best Actor for his extraordinary portrayal of scientist Stephen Hawking in The Theory of Everything. Part love story, part biopic, we saw the film last month and were utterly mesmerised; by the performances, by the score and by the story. Hawking, everyone’s favorite cosmologist, was diagnosed with motor neuron disease at the hopeful age of 21 when he was a rising star at Cambridge. He was given two years to live. He’s now 73 and his place in the heavens is assured. As for Redmayne, he is Hawking’s doppelganger and when he smiles, the entire screen lights up. What kind of cinematic trickery is that?
