I know it was only a joke on Emily's part, but I think Gerard Butler's relationship to alcohol is probably worth talking about. He was training to be a lawyer in Scotland before he wanted to be an actor, and seems to have been a functioning alcoholic - he was kicked off his training one week before he got his certificate, after an incident where he woke up in Paris, covered in blood, with no idea how he got there... He doesn't drink alcohol anymore.
