For my thoughts on our posters I like the minimalist approach. The idea is that the signs will get the subject across easily as long as the subject matter is well represented in its minimal representation and that the viewer is somewhat familiar with the subject. While the subject of these posters are popular movies, our subject should be even more familiar to our viewers. Therefore I think a simple approach is the best action for showing toilets. No need to overkill advertising for such a commonly used subject.
