They're known for their love of pranks and practical jokes, but good friends Brad Pitt, George Clooney and Matt Damon have come together for something far more serious.

The Ocean's 11 stars – all past or present winners of PEOPLE's Sexiest Man Alive title – helped launch an advertising campaign aimed at getting more aid into Myanmar, whose ruling regime has made access to the country difficult for aid agencies and relief workers in the wake of last month's cyclone Nargis.

The ad campaign is sponsored by the activist group Not On Our Watch, headed up by Pitt, Clooney, Damon and other Hollywood heavy-hitters. On Wednesday, the group bought a full page in the Indonesian English-language newspaper, the Jakarta Post, reports the Agence France-Presse.

"Burma's neighbors have the power to help victims who remain desperately in need," reads the ad, which was signed by the likes of former Philippine president Corazon Aquino, East Timorese President Jose Ramos-Horta, Archbishop Desmond Tutu, Nobel peace laureate Shirin Ebadi and former Czech president Vaclav Havel.

The cyclone ravaged the country May 2 and 3, leaving around 138,000 people missing or dead. The ad claims Myanmar's ruling junta is putting in danger thousands of more lives by resisting foreign aid since the storm hit.
