Zombie film:

Location
A quite street near my home, no car passing by.
The car park of Deakin University, which is large and quiet.
A train station looks like the image below.

Fake blood
Making fake blood to make the images more creepy.

Poster
Making a poster that conveys message about zombie, but not saying “zombie” on it.

Indoor shots
Broken mirror, hair on the floor, locked door, shadow on the wall, and so on.

Zombie rules
Break some rules. Make the zombie different from other films.
