Group Opening sequence - planning 1

originally i came up with a storyline which we then planned. the idea was a journey of  different people going to one destination. the three journeys were to be shown simultaneously building tension as to where they were travelling and why it was so important for these people to get there before the other people did.  the plan was to have something really dramatic as opening sequences always or often have something that grips the reader in order to keep them intrested enough to continue watching. we thought we also needed something dramatic in orde to have an effective oppening sequence however we couldnt think of anything good enough that we could do within our limited props and facilities. because our genre being action/thriller is a serious one it must be made to be very realistic. we could have opted to use the tool of a cliff hanger but didnt feel we had given enough of a storyline yet for a cliff hanger to be feasable so we chose to continue brainstorming for ideas
