“They have a huge effect on each other’s lives from the moment they meet. When he proposes in the rain, she says that she knew as soon as she met him that he was the last person she would consider marrying. If you meet someone with whom there is no chemistry at all, why would you think about marriage at all? And while she is thinking how much she dislikes him, she is still thinking about him.”

(Joe Wright, Director)
