George Clooney had to endure some real-life torture when his dura mater, the membrane around the spine, tore while he filmed the 2005 'Syriana,' according to People magazine. Spinal fluid leaked into his body and, at one point, out of his nose.
'I started to have these massive headaches, and I thought I was having an aneurysm,' Clooney said on 'The Late Show with David Letterman.'
