O Nevoeiro

They commit suicide or they have someone kill them which is the same thing as what I said up above.

Starts out with a mysterious fog that causes things to go mad and crazy which sounds a lot like the news here.

Infects the brain and infects the lungs eventually drives them crazy where they either kill themselves or they kill each others... There's really not a lot to this movie it's quite boring and depressing... You're better off looking for some thing else won't make you feel sick about the planet dying and then the people dying off... Apocalyptic movies always are very down on everything... What you sow is what you reap I believe that's Bible...
