Generally, as we edge closer to any movie with play-appeal, the toy lines will spoil plot devices, super powers, hidden characters and even entire lines from the film ..if you aren't careful to avoid them. The second line of merchandise you have to steer clear of is kid's books, which release even further in advance of these films and can tell the WHOOOOOLE story in terms so simple, a two year old will get it...which is sort of the point.
