HEADING into the final chapter in the Shrek series of films, comedian Mike Myers admits to sharing Shrek's insecurities.
The man behind the Scottish brogue in Shrek Forever After, the animated 3-D film about a good-natured ogre, says he's secure enough to admit he is quite insecure.
"Growing up in Canada you feel like you walk amongst Americans, but you are slightly different. I think ogres feel slightly alienated," he said.
"I have a whole childhood I can't talk to Americans about and that is Canadian TV. I'll be like 'Oh, it's like on Mr Dressup or The Friendly Giant', and they'd be like 'We don't know and we don't care'.
"It is an odd, double life we lead. Things like the Queen. In Canada you see the Queen everywhere, but in the US you don't."
The fourth film of the Mike Myers-voiced animated series features the villainous Rumpelstiltskin, who takes advantage of Shrek's mid-life crisis and tricks the ogre into doing a deal that changes history and puts Rumpelstiltskin and thousands of witches in control of the Far, Far Away kingdom.
Cameron Diaz returns to voice Princess Fiona, Eddie Murphy is Donkey and Antonio Banderas is an overweight Puss in Boots.
Myers says that before doing Shrek he didn't think animation could move people or make them cry, and now that it is ending he is feeling sad.
"The more I talk to Antonio (Banderas), Cameron (Diaz) and Eddie (Murphy) about it being the end, the sadder I get,' he said.
"I'm glad I was part of it. When each Shrek film came out I saw how much people care about it. They care about it as much as I do. I think 'Wow!' So, I'm very grateful and appreciative and proud about being part of it.
"I'm also proud how they are ending it very gracefully. It's like what they do on British TV. I think it's smart it just comes to an end so eloquently."
Myers says the biggest challenge in playing Shrek was the New York lifestyle.
"The biggest challenge is getting into the world of Shrek in the first 10 minutes when I come into the recording studio," he said.
"I live in New York City and it can be an overwhelming place to live. One time, I walked past the scene of a murder and then went in to work on Shrek.
"I had to shake that experience off. Then I had an experience where I finished work on Shrek for the day, walked out and walked past a murder."
Myers says its gratifying that Shrek as a character has been called iconic in the ilk of Mickey Mouse.
"For me, I love Fred Flintstone and Bugs Bunny. To even be considered in the same realm as that is amazing.
"Jeffrey (Katzenberg) said to me 12 years ago 'Would you like to be in an animated movie called Shrek?' and I said 'That's a bad title'. The moral of the story is don't listen to me (laughs). What do I know?"
Shrek Forever After opens in Australia on June 17.
