Emma Watson has revealed that it was difficult to make her kiss with Daniel Radcliffe look passionate because they are like brother and sister.
The first part of the final Potter instalment, Harry Potter and the Deathly Hallows, hits the big screen this week and Harry and Hermione lock lips in the movie.
But the young actress admits that it was very awkward.
Speaking to MSN Movies the actress said: "I'm proud of it, and considering how b****y awkward it was, I'm really impressed we managed to make it look anything other than awkward - because Dan and I are like brother and sister, so it was tough making it look passionate.
"I realised I would have fewer takes to do if I just got on with it and just gave David what he wanted, which was a passionate kiss.
"Which was something that would really rock Ron's boat and really be quite painful and nasty for him to watch.
The second half of the movie will be released next summer and that will bring the Harry Potter franchise to a close.
Harry Potter and the Deathly Hallows: Part 1 is released 19th November.
