The Kiss Was Improvised And Awkward
At the age of 18, the actress did not have a lot of kissing experience under her belt. Even though she was surprised to hear this suggestion from the production crew, she rolled with it. If you watch the film, you should know that the kiss was totally improvised. According to Carter, it was also a bit awkward.
