Speaking to a UK newspaper, she said: ''I've never had any problem with the idea that there is other life in the universe.
''Does that life look exactly like us? Probably not. In fact, I couldn't even imagine what these other life forms might look like, or what set of values they might hold or knowledge they might understand.''
The 31-year-old continued, telling the Mail on Sunday: “I’ve always thought it's highly unlikely there's nothing out there. I certainly don't struggle to believe that they exist.''
Anne stars in new sci-fi flick Interstellar as an astronaut, but it turns out that she never shared the same aspirations to go into space.
''I did want very much to go into space when I was little, but I was very bad at both maths and science when I was at school soI could never even dream about making that journey.”
As an adult, however, she became more interested in space.
''Then, when I was older, I started to watch a lot of nature documentaries, which later led to documentaries about science, about physics, about the universe.''
