The 32-year-old Australian actor plays the mysterious Marcus Wright in the movie, which also stars Christian Bale and Moon Bloodgood.
Says Worthington of his character: "Here's this person waking up in another world and trying to find himself as they go on this yellow brick road."
Worthington notes that his character wears a blue coat, just as Dorothy wears a blue dress in "The Wizard of Oz."
Bloodgood says Worthington took the "Oz" comparison even further: "He actually put red paint on the back of his shoes, like Dorothy trying to find her way home."
"Terminator Salvation" opens Thursday.
