Offspring's Lachy Hulme has a secret "mission" every time he acts opposite Asher Keddie.

Nina Proudman and Martin Clegg: could we possibly love the Offspring characters more than we already do?

As it turns out, yes we can.

In a new interview Lachy Hulme, who plays Dr Clegg, has shared what really goes on behind his dramatic scenes with co-star Asher Keddie.

“To make Asher laugh while the cameras are rolling is my mission. If I can make Asher lose her s*** in a scene I go home a happy man,” the actor told News.com.au.

“I make notes. I think ‘I might be able to get her on this one [scene] today.'

"Asher and I feed off each other. She gives as good as she gets. She comes in prepped for me, too."

Sometimes, Hulme admits, it gets to a point where the two actors can't look at each other during dramatic scenes because they'll just burst out laughing.

“[W]e went to dinner and I said, ‘We’ve really got to pull it back or we won’t get any work done if this keeps going’," Hulme added.
