Washington, October 14 (ANI): George Clooney and Ewan McGregor were left trembling after a huge earthquake shook the foundations of their new film's sets.

The duo were shooting in Puerto Rico for their anti-war satire 'Men Who Stare At Goats' when they were hit by a strong quake.

Though the officials reported no injuries, the quake was said to be the country's strongest in 20 years.

Interestingly, the quake came on the 90th anniversary of the most major earthquake ever recorded in the Caribbean that killed 118 people, reports Contactmusic.

The forthcoming movie, which stars Clooney sporting an unusual look including a moustache and long hair, was chosen to be shot at the island for its closest resemblance to a war zone. (ANI)
