Maddox Jolie-Pitt has reportedly been cast in his first movie.

The 10-year-old adopted son of Brad Pitt and Angelina Jolie is set to take the lead role in 'Battling Boy', a movie based on a graphic novel that is being produced by the actor's Plan B company.

A source told the Daily Star newspaper: "Te film is based on a graphic novel about the young son of a god who leaves his mountain-top home to fight monsters.

"It's being produced by Brad's Plan B production company.

"Maddox lives, eats and breathes movies and comic books, so Brad and Angelina thought he would be perfect for the starring role."

Angelina has previously praised Maddox - the eldest of the six children she raises with Brad - as a "real intellectual".

She said: "Maddox is a real intellectual, which I can take no credit for genetically. He's great at school, great at history.

"He feels like he could be a writer or travel the world and learn about places and things."

The 'Tourist' actress has also previously admitted she enjoys taking part in action movies because she wants her children to be impressed.

She has said: "The funny thing about having children is that now I am twice as motivated to do a cool stunt because my kids will like it.

"I'm very responsible these days not to be self-destructive because of my kids, but at the same time I have all the more reason to do all the cool things possible because I want to try and make my kids proud."
