According to director David Yates, this last part of the scene after Harry’s first kiss wasn’t in the script. After the 3 actors had said their lines, Emma Watson started laughing hysterically. David Yates thought this would be a good addition to the movie, so he kept rolling. I think, this is one of the most beautiful scenes of the entire series of movies. It shows us one of those moments when Harry and his friends really got to be just teenagers who had the liberty of getting excited about each others’ first kiss, instead of worrying about the next big hurdle in the path of righteousness.
