Thread: looking for a certain movie, possibly short film?

I remember watching a preview of it a year ago, and lately I've been seeing it come up on tumblr, but I don't know the title of it.

Its pretty much revolving around a zombie who thinks normally? and wears a red sweater, and its like a world of zombies or something like that

You might be thinking of Warm Bodies. Not sure if that's what you're looking for.

Warm Bodies
It is out in theaters now
