The Australian comedian, whose most recent show Angry Boys tells the stories of manipulative Japanese mother Jen, teenage twins Daniel and Nathan Sims and their "Gran", said that he has realised that he creates "frightening" women.
Lilley told The Age: "[Jen is] the meanest, most awful character I've ever done. [My women are] the most frightening. I realised about halfway through the show that I portray men as really dumb and women as really crazy. What's happened that I'm seeing the world like that?
''They're a real struggle and I'm just dreaming of the next character whenever I'm shooting them. Gran was probably the hardest. It was physically quite hard to be in that suit the whole time. It was the hottest time of the year and really uncomfortable.
''When we shoot stuff, it doesn't seem that funny. It becomes funny in the way that it's cut together. So when we shot Gran, I felt like they were all looking at me and going, 'Do something funny.'
''I'm really happy with the show... with every character and every little world. But I'm sure some people will have preferences for some characters.''
His long-time producer Laura Waters said that they wanted their latest project to be a "challenge" to make it more "fun" and believes that they have "taken everything to the next level".
She also revealed that during filming there was a lot of "tension" on the set because Lilley makes himself so "vulnerable" but added that she "marvels" at his talent.
Lilley said of Waters: ''She is very protective of me. On this show, she was on-set all the time. If anything went wrong, she was right in there. It's like she's out front with the torch making sure that all the baddies are out of the way while I'm skipping along behind. It doesn't suit my personality to be bossing people around. She's tougher with that."
Angry Boys premieres in Australia tonight at 9pm on ABC1.
