Rosario Dawson struggled with allergies on movie set

Rosario Dawson was well medicated on the set of her new movie The Zookeeper - because she's severely allergic to animals.

The actress plays a zoologist in the comedy but she wasn't laughing when she realized she'd be sharing the screen with so many creatures.

The Sin City star explains, "I'm super-allergic to animals, so I was really medicated while making this movie. I had to take nose spray, eye drops, face cream and pills, because I get hives and get super itchy.

"I've actually scratched my eyes so much I get scabs on the inside."
