Who to take: This one's going to be a big people pleaser, so you've got a wide range of guest options. Since there are romance, action, and comedy elements, most people should walk away with something to say.
Who to leave: Anyone who says space movies aren't their "thing." And anyone who was just never really on board with Jennifer Lawrence, for whatever weird reason. Also, that science nerd in your life who'd be all like, "That would never happen!"
