London, Jan 3 (IANS): Actress Sofia Vergara, who gave voiceover in "Happy Feet Two", says she deliberately asked for a smaller role as she was reluctant to give her voice for the movie.

"I knew it was a small role when I did it. It was my first time doing a voice for anything, so I didn't want it to be a big role because I didn't want to not be able to cope with it," contactmusic.com quoted her as saying.

"I'm quite new to acting, so I prefer to do little things that I think I will be ok to do, rather than bigger parts where people are thinking, 'What is she doing', "she added.

Sofia, however, has found the creative process "very easy" and accepted the offer "immediately" when she found out she would be acting alongside Robin Williams, Elijah Wood and Matt Damon.

"I wanted to do a film like this for kids and give out a nice message and it's not like I had to do hours and hours of research for this role. It was very easy. I knew I was going to be part of such an amazing cast so I said yes immediately," she said.
