The most compelling reason for me to think it's a man is the sequence leading up to the opening of the dutch doors. I see broad shoulders and a slight hunch (more than slight, actually).

That head is definitely leading the charge, here... and the turnout of that right foot is clearly affecting their walk, like you would see in some people with back problems (sciatica), polio, or a hip injury... a slight "jounce" when stepping with the right...
It's a walk I recognize, and have seen before, but it's so hard for me to describe... I'm picturing a 20 something man, out of shape, with horrible posture, dragging his feet like some lethargic, dull-witted gaming addict.. I'm really not seeing a person wearing lifts or "acting;" I'm seeing a genuinely screwed up man.
**EDIT: I'd love to see one of you fancier types overlay a skeleton on this still frame to show what I mean (if it makes sense, that is)
