Ideas for the opening sequence

This Youtube clip is from a BBC drama called Survivors although it is not an opening of a film it is based on a similar idea to ours where there is only a few people living and they have to come together to fight off a disease. In this short video clip a wealthy playboy wakes to find girl he met the night before dead in his bed, a young boy is surrounded by dead bodies in a mosque and so is a charismatic and dangerous inmate in a prison; a brave new world is emerging and the survivors must unite and stand together or die. In our film the dead bodies would most likely turn into zombies as is it will be a teen horror and not a BBC TV drama. When I first watched the clip I found the whole concept entertaining and I was in suspense/shock as I didn't understand what had happened, if this feeling was created in our film it would engage the audience and could result in a good film opening.
