George Clooney is getting politically charged again.

The outspoken actor has bought the rights to Jonathan Mahler's legal thriller "The Challenge," which centers on the attempts to ensure a fair trial for Osama bin Laden's bodyguard/driver Salim Hamdan, reports Variety.

Clooney and Grant Heslov's Smoke House banner will develop the project, which may be a writing, directing and starring vehicle for Clooney.

On Aug. 7, the Yemeni-born Hamdan was sentenced by a panel of military officers at Guantanamo Bay to a prison term of 66 months, including time already served. Although he was found guilty of material support for terrorism, he was cleared of the more serious charges of conspiracy to commit murder.

Smoke House also has other politically charged projects in the works, including "Escape From Tehran," "Men Who Stare at Goats" and "Our Brand Is Crisis."
