Anne Hathaway has been making the interview rounds recently in support of her upcoming movie, "Serenity." This week she appeared on "The Ellen DeGeneres Show" and shared a funny tidbit about her time filming the movie. "Serenity" was filmed on Mauritius, an island off the eastern coast of Africa. As USA Today reports, while she was there, Hathaway and her co-star Matthew McConaughey visited some rum bars on the island, along with McConaughey's wife, Camila Alves. When DeGeneres asked how the rum bar tour went, Hathaway laughingly replied, "I don't remember. I have no idea." Hathaway further explained, "They're both cool, and I'm not, and I just can't drink as much as them." The day after the rum tour, the Oscar-winning actress had to go to a meeting with "Serenity" director Steven Knight, and she said that she was "just kinda stumbling in with one eye open and I was trying to convince him about certain things about my character." After that experience, Hathaway revealed in October 2018 that she stopped drinking, and plans to continue to stay sober until her 2-year-old son, Johnathan, turns 18."I’m going to stop drinking while my son is in my house just because I don’t totally love the way I do it, and he’s getting to an age where he really does need me all the time in the mornings," she continued. "I did one school run one day where I dropped him off at school, I wasn’t driving, but I was hungover and that was enough for me. I didn’t love that one." DeGeneres then quipped, "That's another reason why I don't want kids."You can watch the full interview here.
