`Harry Potter` films not "selling sex" like `Twilight`: Watson

London: Actress Emma Watson, who plays Hermione Granger in `Harry Potter` films, says that her much talked about kiss with co-star Rupert Grint was awkward.

Taking a swipe at `Twilight` movies, Watson said filming the intimate scenes was difficult because unlike vampire romance, `Potter` films are not selling sex. "This kiss between Hermione and Ron is highly anticipated, it`s been building up for eight films now. And `Harry Potter` is not Twilight`, you know; we`re not selling sex. So, whenever there is any hint of that, everybody gets terribly excited. In fact, it was horribly awkward; we couldn`t stop laughing," the 20-year-old star said. The pair discussed their intimate scene in great detail before they finally kissed, and agreed that feeling uncomfortable would be worth it if it looked good on screen, Contactmusic reported. "The nicest thing about it was, before we did it, we turned to each other and were like, `God, this is going to be awful, isn`t it?` but hopefully it will look good," the actress told Empire magazine. `Harry Potter and the Deathly Hallows` will release in two parts, with the first part coming out in 2010 and the second in 2011.
