Worthington felt like an infant opposite Neeson in new film

London: Australian actor Sam Worthington felt like an "infant" on the sets of new film ‘Clash of the Titans’ because he was vying for screen time with veteran actors Liam Neeson and Ralph Fiennes.The 33-year-old shot to fame starring in hard-hitting action movie ‘Terminator Salvation’ before taking the starring role in James Cameron`s massive hit ‘Avatar’, which has become the highest-grossing movie of all time.

But despite his recent success, Worthington insists he still felt overwhelmed having to act opposite Neeson and Fiennes on his latest movie, reports imdb.com. "It was intimidating. Liam is the big boy. When you`re playing with the big boys, you man up and listen," he said. "Liam acts with such grace. He`s a gentleman and an imposing force on screen. You observe what he can do on set and he gives you advice on how to handle all this and the outside world with some sensitivity. Same with Ralph. Collectively, there`s 100-odd movies between them, so as far as an infant like me is concerned, you listen," he added. IANS
