Harry Potter star Evanna Lynch is the latest celebrity to take part in one of Animal Equality's groundbreaking virtual reality films.
The vegan celebrity, famous for her role as Luna Lovegood, narrates the film which exposes the dark reality of dairy farming.
Talking about her role, Lynch said: "I just wanted to like make myself as small as possible and I was thinking that must be how the animals feel, that they just want to hide, but there's not any corner of comfort or peace in any part of their lives.
"It’s so cruel and so horrific, and if you’re spending a few dollars to support this — it’s just not worth it. If you’re actually paying to support this you should know where your money is going or you should take ownership of what you’re doing.
"I think it’s the passivity of most people that makes this OK, that makes it go on. And the fact that it’s all behind closed walls."
iAnimal uses cutting-edge virtual reality technology to give viewers an immersive look at the life cycle of farmed animals from birth to death.
This latest project features brand new footage filmed by eight investigators in three countries over six months, including heartbreaking scenes from three British dairy farms.
Jose Valle, Animal Equality’s Co-Founder and Director of Investigations, said: "Experiencing iAnimal can be just as haunting and life changing for people as visiting any of the 120 farms and slaughterhouses I have investigated around the world.
"Animal Equality is grateful to Evanna for giving voice to the billions of animals who suffer and die on factory farms each year and educating people on the dark reality of dairy farming.
"iAnimal is the closest you can get to experiencing how animals raised for food live – and die – worldwide. If you care about animals, the environment, or where your food comes, you need to see this."
