Mike Myers has revealed Shrek was originally Canadian.

The actor - who is the voice of the ogre - experimented with several different voices before he finally settled on the animated green hero's trademark Scottish tones.

He said: "Shrek's voice was originally Canadian because that's where I'm from. Then it was based on the voice of a character I did, Lothar of the Hill People. But, I would do it for 10 minutes and couldn't talk for three days. It took too much out of me.

"I have some Scottish blood. Scottish people are the salt of the earth. They are also capable of being very angry, but then very loving. I thought that would be perfect for an ogre. It is also a working people's accent. I feel ogres are working people. I seriously put that much thought into it."

The 47-year-old comedian went on to add that he has some similarities with his Shrek alter-ego.

He explained: "Insecurity. I'm secure enough to admit I'm quite insecure. Growing up in Canada you feel like you walk amongst Americans, but you are slightly different. I think ogres feel slightly alienated."

Mike also admitted that while he will be very sad to see the end of the 'Shrek' movies, he thinks it is coming to a close at a good time.

He said: "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."
