Ideas for extra footage

In our lesson our teachers watched our film and we all agreed that a good way to improve our film would be to introduce dialouge in it. Thisd would give our film a more realistic atmosphere. We decided we should have the girl shout something when luke walks into the room that she is trapped in, saying something like 'what are you doing?!' or 'who are you?!' and then luke would reply to her. Before we just had a reaction shot of the girls face looking scared, but thought that this was unrealistic and boring. we would also need to think about if the girl knows the man, becuase if she did, then it would be a different reaction to if he was a stranger.
