But dinner was usually only the beginning for the indestructible cast and crew.

"There's a place called the Victoria Room. You can take a big group of people there, and they have, like, really big round tables, and it's all tapas," she says, before changing directions. "You know what actually is very indicative of Sydney? They're famous for their barbecues. You would go to a friend's house at night for barbecue, hang out until the wee hours of the morning, and then go home, sleep, come back sort of in the afternoon, have a Bloody Mary and barbecue again, and then go just have a sunny Sunday afternoon. Their way of life is just so incredible. I mean, I would absolutely love to live there one day."

Some days, she flew to lunch or dinner, not with Superman, but by seaplane. "They would take off and land right outside my window, which was really fun. You take the seaplane about 45 minutes and land on a river, and you pull up to a restaurant called the Cottage Point and Inn Restaurant. And the only way to get there is by seaplane. I suppose you could take a boat, but it's a bit more tricky."

IN THE LAST MONTH of Bosworth's working sabbatical, she got a visitor.

"My mom came out to visit me for a week," she says, and so they did some of the touristy things. "When you live in a city, you sort of don't really do the tourist things. But when somebody else comes to visit, you start thinking of the things that you can take them to do."

The most obvious thing was right outside her window: to climb the Sydney Harbour Bridge. "It's incredible, because you get a history lesson of Sydney; the way they built the bridge was just incredible. They have to secure you to railings on the bridge the whole time you're climbing. You literally climb the outside, up the outside of the bridge. I mean, your whole body is free. You're just attached by - what do they call those things when you mountain climb? A carabiner."

She didn't do this with Superman; she did it with her mom.
