This is a similar film to my second idea for a short film as they follow a similar plot that people need to escape a place they are in as in my film the place has been infected and taken over by zombies but in this film the UK has been infected by a virus.

This is a similar film to my first idea as it is a short thriller film as mine would be it also includes a similar storyline as the "gang" in my film want to extract revenge on the boy who hurt the member of their gang so they take revenge on the people that hurt them.
