Sam Worthington: For Those About to Rock...

Sam Worthington arrives at LAX airport on Wednesday (March 24) rocking an AC/DC shirt.

The 33-year-old Aussie actor was joined by his stylist girlfriend, Natalie Mark – the two were headed to Heathrow airport before the UK premiere of Clash of the Titans!

Sam recently spoke about an Avatar sequel (via NBC Washington)! “Jim had an arc for three,” he shared. “Three’s a great number. It’s the number you want to do. But we didn’t even know we’d go into a second one until [Avatar was] fully embraced.”

“The fact that it got embraced so quickly and so amazingly, which is mind blowing for all of us, means an audience wouldn’t mind going back to Pandora with us. But if you do the second one and it’s terrible, you don’t do the third one. It all depends on the audience. That’s why you make movies.”
