Natalie Wood's a great shout, but if I could only have one it'd have to be the beautiful German actress Brigitte Helm. Or Steven Jay Gould, Rik Mayall, John Martyn, Friedrich Nietzsche, Fyodor Dostoevsky, Simon de Bolivar, Layne Staley, Tim Buckley, Billie Holiday, Arthur Rimbaud, or someone from my real life. Or, better still, Plato, but only so I could kill the cunt all over again.
Oh, it's too hard to choose just one person, so I guess I'd bring back some long-forgotten serf from the 14th century just to see the look of surprise on their face as they were resurrected into the 21st century.
