After playing an underdog in "Slumdog Millionaire", Dev Patel is all set to play a negative role in his new film "The Last Airbender".

The 19-year-old has gone for a mean look quite opposite to his character in the multiple-oscar winning film "Slumdog...", reported thesun.co.uk.

In the film, which is based on an animated TV series about warring elements of Air, Water, Earth and Fire, Dev will essay the role of a character called Zuko.
