The Australian comic, who returned to BBC Three last night with new comedy Angry Boys, revealed to Digital Spy that he would never rule out bringing back some of his most popular characters from previous shows.
"I love bringing the characters back. Ja'mie was in two shows, Mr G was in something called the Big Bite as well. I love bringing characters back," he said.
"But I mean, when I did Summer Heights High everyone was saying, 'you'd be mad to not bring Ricky Wong back' and they wanted everyone from We Can Be Heroes in it. So a lot of a people were disappointed with Summer Heights High. Someone is always missing out.
"But bringing characters back is exciting for me. No time passes for these characters, so it's fun to think of them being on pause and that they could come back at any time. I really love those characters so it would be cool to bring them back."
Lilley also confessed to being unsure about moving into the world of movies, claiming that the format of TV shows suits his needs better.
"When I wrote We Can Be Heroes, I was just so excited about the concept of playing loads of characters and a television series allows you to do that," he said. "It's also an event that you tune in for each week and people talk about where it's heading.
"This show is so huge, it's 12 episodes, it's like writing three or four films. It's so massive. It's more that I'm more excited about TV than me not being interested by film. I know film has that prestige and everyone says, 'you should do a film next'. I just think so many more people see television.
"But maybe one day I'll do a movie. The problem is that I've written things in episodes for so long. It would be an interesting challenge."
