London: Brad Pitt and Angelina Jolie's eldest child Maddox has reportedly landed his first movie.

The 10-year-old adopted son of the couple 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, according to reports.

"The 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,” a source said.

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

Jolie has previously praised Maddox - the eldest of the six children as a "real intellectual".

"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," Jolie said.
