Cameron Diaz wishes she had done her Shrek character of Fiona with a British accent.
The actress is back voicing the ogre in Shrek Forever After, the fifth movie in the highly successful franchise.
She admits that if she had known that her parents, who appear in the second film, were going to be voiced by Julie Andrews and John Cleese then she would have done things differently.
In an interview with About.com she said: "If I had known that Fiona's parents both had British accents when I first started - that they were being voiced by Julie Andrews and John Cleese, I might have, you know.
"Because when I first started the movie, when I did my voice, I didn't know who was playing my parents.
"So it was one of those things where I was like, 'Wait a second! How come I sound like I am from California?'
Diaz, who is also in action with Tom Cruise in Knight And Day this summer, believes that the movies have been such a big success because they 'speak to everyone' and are suitable for adults as well as children.
"You're never too old or too young to learn these lessons, and I think that's the case with all the 'Shrek' films and why they're so successful.
"They're not just speaking to one audience, they're speaking to everyone. Anyone who watches it can understand exactly what Shrek and Fiona are going through relevant to their own lives."
Shrek Forever After is released 2nd July
