Rachel Weisz had a close call while riding a horse trained for 'Game of Thrones'

Working with stunt horses is no simple task, especially if it has been trained to work on Game of Thrones.

In the video above, Rachel Weisz tells Graham Norton what it's like to ride a horse that was previously employed on Game of Thrones.

While working on her latest film My Cousin Rachel, Weisz rode a horse that was was specially trained to die on command. Unfortunately, she accidentally pulled that special trigger while sitting on top of the 1,000 pound beast. Thankfully, she wasn't seriously injured.

"It wasn't unpainful, but it was okay," said Weisz.

Phew. Rachel Weisz said not today.
