Clash of the Titans “stars Sam Worthington, but you will have guessed that already. These days, no major production is allowed to embark without him. He is the strapping Australian lad who, without warning, has found himself cast as a cyborg, in ‘Terminator Salvation,’ as a would-be alien, in ‘Avatar,’ and now as the demigod Perseus, in ‘Clash of the Titans,’ while retaining the look of someone who cheerfully expects to be returning to a steady job on a building site.” EXACTLY! EXCEEDS EXPECTATIONS! A++! WOULD DO BUSINESS AGAIN!
