You've Got Mail, starring Tom Hanks and Meg Ryan, is the modern world's first rom-com about the joys and perils of online dating. The two characters, Joe and Kathleen, fall in love while sending each other messages in an AOL chat room. The twist? The pair are bitter rivals in real life, and only one of them knows it. When Joe finds out his digital pen pal is the owner of the bookshop his giant retail chain is trying to conquer, he doesn't share this knowledge with Kathleen.
