Orlando Bloom and Liam Neeson are in talks to star in an as yet untitled movie based on Bill Carter's book, Fool's Rush In.

Variety reports that the pair look set to join Javier Bardem, who is also being lined up to star in a supporting role.

The trade says that Carter wrote the book about the period of time when he lived and worked as an aid worker in Sarajevo during the bitter Balkans war siege that lasted 43 months.

"I read the script, and the very human story and the very core of this film spoke to me very clearly," Bloom told reporters in Sarajevo. "This is a departure from the very big Hollywood productions."
