The cast of Watermark all deliver great performances. In a film with little dialogue, it's exciting to see a group of actors bringing such depth to their performances. Jai Koutrae, being present in almost every scene, exudes emotion. Watermark is just amazing for its really strong performances. In an interview, the cast said they worked a lot with the director in rehearsals on the methods of unspoken communication and you can see the results in the finished film. Another aspect of the film that sets it apart is the way in which the characters' emotions are drawn out through the visual imagery. It's rare to achieve such heights in feeling without recourse to the spoken word. The water almost becomes another silent but powerful character in the film. It envelops the characters.
