'Equals' shows Nicholas Hoult, 25, and Kristen Stewart, 24, living in a futuristic world where all human emotion has been eradicated.

The two play lovers in the film, reported E! Online.

"She's so talented. I really can't speak highly enough about her. She's a talented, lovely and a wonderful girl...

She's just got such a smart approach to her work and she's a real artist," he said about Stewart.

"My character starts to get what they consider a sickness, where he starts to have nightmares and feel things and he's like, 'Hang on! What's going on here?'

"And then he notices Kristen's character and they start to develop this relationship in a world where people aren't allowed to have relationships, where they don't exist. It's basically a love story."
