According to TMZ, more than 200 security guards were hired to escort lead actress Lena Headey as she walked naked through the Croatian city of Dubrovnik.

On the set of the hit show in Dubrovnik, Croatia.

The scene, which will appear in the show’s fifth season, involves Headey’s character, ruthless royal Cersei Lannister, doing a “walk of shame” through the city of King’s Landing.

During the four-day shoot, which drew hundreds of curious tourists, shop owners were reportedly paid to vacate the area, mobile phones were banned and confidentiality agreements were signed by everyone involved.

One photo, however, slipped through the cracks, revealing a back view of Headey naked and covered in dirt and blood.
