Sam Worthington has admitted he was "a jerk" for instigating an incident that ended in his arrest for disorderly conduct in Atlanta, Georgia last year.
The Aussie joined the celebrity mug shot gang after getting into a fight outside a restaurant in November while he was shooting a movie in the city.
"I was a jerk. It was my fault," Worthington told News Limited.
"I've admitted it. I was a jerk, I was in the wrong. Move on. That's it."
Asked if alcohol played a part in the fracas, the actor gave no excuses.
"No, I was an ass!"
Worthington reportedly screamed he was a DEA agent after he was pepper-sprayed outside Vortex Bar and Grill.
He allegedly threatened the doorman who sprayed him, screaming: "I'm a DEA agent! You f***ed up now!"
Police told TMZ that staff said Worthington was intoxicated and unable to provide valid identification.
A witness told authorities that he pushed doorman Jerry Link twice. Mr Link allegedly responded by pepper-spraying the actor and putting him in handcuffs until police arrived.
Worthington, whose new Aussie movie Drift opens on May 2, is on standby for an Avatar sequel.
"Jim (Cameron, director) is still writing it," he said.
"Supposedly end of the year, but they said that last year, so it’s up to the boss. Whenever Jim says, 'Let's go', we're gonna go."
Worthington, 36, is contracted for two more Avatar films and calls the mega franchise his "safety net" as he hunts for a more challenging career path.
Ten, the action thriller he shot in Atlanta with Arnold Schwarzenegger, sees the star transform into a bald, bearded tough guy.
Schwarzenegger last week praised his young co-star for his determination: "He likes to do all his own stunts, he is a go-getter and a great actor," said Arnie, apparently anointing the Australian as a worthy action hero successor.
"Arnold's very nice to say that," Worthington responded. "I got on very well with that guy.
"He's an icon and you shake every day when you see him, because you grew up watching his movies, and going from pumping iron to controlling one of the biggest economies in the world.
"That guy has set out and conquered everything he’s ever wanted to do. So any kind of compliment from Arnold, I'm completely humbled by it."
