Everyone ever should watch (and love/be fascinated by) Pontypool.
Linguistic puzzles and zombies in one film? What more could I ask for!?
It is set in Canada, you say? EVEN BETTER.
If you never thought you would ponder the problems of living in a bilingual zombie-state, you should probably start living your life more realistically, and then go watch this movie.
Seriously. I don't know how I lived and loved zombies before this.
Its going to be a lot harder for Zombieland to wow me now, unless they happen to have a few jokes at the expense of French Canadians thrown in there for good measure.
