Filming of short opening sequence

On friday me, Karl and Gina filmed a short 45 second opening sequence to a film. we used Karl as the male character and an extra called Natasha to play the female character. The plot was simple, boy meets girl he fancies in the hall way at college and asks her about her holiday and her boyfriend, he ofers his support and sympathy to her when she says its not going so well with her boyfriend and gives her his phone number. They walk off and he is then humiliated by bullies walking in the other direction, played by me and other classmates.

Working with karl and gina was a lot of fun, we were working and getting all the shots done to a good standard whilst having fun which shows our determination and skills in working together in a group. However, i found it difficult working with one of the extras who we picked randomly from a group of people walking in the hallway. He didn't seem like he was taking what we were doing seriously and caused delays in filming time, eventhough we finished early and were able to be in another groups film. After Paula spoke to him we got the first shot in and out of the way, which was of karl walking down the stairs behind a group of college students and into the hallway where the scene was shot.

From this experience i have learned that before filming, to save having to re-take a shot we will need to fill the actors in on exactly what we want them to say, when we want them to say it and how we are going to film it so there will be no confusion. Also, we will need to know exactly who we are going to chose to play a roll as an extra or main character instead of just picking random people to do the shot because they are unprepared and we don't know whether they are going to take the situation seriously.
