Transformers: Age of Extinction Principal Photography Wraps

Due to the recent script alterations, the crew was forced to once again visit the Three Natural Bridges scenery of Fairy Maiden Town in Wulong County on Monday, and used two helicopters to get several grand aerial shots of the tiankengs (giant dolines) and naturally formed bridges on Tuesday and Wednesday. The scenes they shot will be used in "Transformers 4" to add visual impact.

The fourth instalment of the "Transformers" franchise has just finished part of its shoot in China, and it features some beautiful natural scenery.

This cave, located in Wulong county of Chongqing Municipality, is a naturally formed karst landform. It was chosen as a location for the shoot of Transformers 4 for its breathtaking grandeur.

The final cut of this scene is about 2 and a half minutes. The shooting is mainly for a bird's eye view of the two bridge-like landforms, and a fight scene between transformers takes place under them. Then a transformer walks out from below the two "bridges". Huang Daosheng, Manager of Wulong Karst Landform Co., said.

Because the bridges are part of a world natural heritage, the film crew did a thorough test to make sure the shoot would not damage the bridge. The shoot has also lured a number of curious tourists to the site.
