The 12-part mockumentary series - a co-production between Aussie broadcaster the ABC, HBO and the BBC - sees Lilley play a variety of new and established characters in an exploration of "being male in the 21st century". Returning characters are thought to include Phil Olivetti from We Can Be Heroes and Ja'mie King, last seen in Summer Heights High.
The project was first rumoured two years ago and entered pre-production in October 2009. Filming began in Australia in February 2010.
"That team are perfectionists and they're not going to release anything until they're 100% happy with it," Brendan Dahill, channel controller for ABC1, told TV Tonight. "And what I have seen I'm more than 100% happy with."
He added: "This is Chris at his best. It’s going to blow people away."
