Before the multitude of the crappy zombie movies you've seen lately, back in the day in 1992, Australia was producing a zombie movie that remains cool even today, made by a little known New Zealander called Peter Jackson. It mixed zombies with comedy, original ideas and wacky Aussie characters.
23 years later Wyrmwood is an obvious homage to Braindead, but adding a few elements of its own. The main character, almost a dead ringer for Bruce Campbell in The Evil Dead, is trying to get to his sister's place in the middle of a zombie plague. Not only are there zombies everywhere, but petrol has become not flammable. The only solution: rig a car to the gasses that zombies breath out and make an armored truck running on zombies. Meanwhile, the sister is being captured by sadistic psychopath military types in order to experiment on her.
There are many references to cult films, like The Evil Dead and Mad Max, and the ending of the film leaves a lot of place for sequels. This is not a perfect film, but considering that it is an Australian zombie movie made with unknown actors and probably a low budget, there was no chance it could have been. Instead we are treated to a wonderfully original film, made by people who clearly enjoyed playing with the genre and love the same movies that we do.
Bottom line: more than anything, this is a fun film. If you liked Braindead or The Evil Dead you will like this one as well. It opens an interesting idea, also used in the season finale of Z Nation, of the zombie whisperer. People die or live based on luck more than anything and it is refreshing to see this in an era when nobody ever dies, for fear of antagonizing the viewers. I recommend it, I enjoyed watching the film!
