Budding Heath Ledger impersonators gathered in a park in Sydney to compete in one of a wave of celebrity lookalike competitions popping up in cities across the world. Contestants were also judged on their best impersonation of the late Australian actor and their ability to sing Frankie Valli's 1967 hit Can't Take My Eyes Off You – a reference to Ledger's character in 10 Things I Hate About You. 'I saw lookalike competitions happening around the world and I kept waiting for someone to do one in Sydney, and no one did, so I though we should have a crack here,' organiser Joshua Khoury said.
