George Clooney’s Head Injury Required Surgery.
It comes as a surprise that George Clooney wasn’t hurt when being beaten up in Syriana. Since he was restrained to a chair, we can only assume that it was actually him performing the stunts. Still, he messed up throughout this particular sequence. Clooney was being “beaten up” when he toppled over the chair to which he was still bound and struck his head on the concrete floor. They hit him so hard that he suffered a concussion and continued to suffer from headaches long after the film ended. Soon after, he underwent surgery to correct the issue.
