This film is a bit different than most because is filmed for dual screen, meaning that during every scene there are 2 cameras capturing the action. Usually we are shown the same event from different angles, other times the 2 sides are splits in time, so we see the past and present. The main characters, played brilliantly by Helena Bonham Carter and Aaron Eckhart, meet as participants in a wedding and rediscover their past. The dialog is brilliantly written and the acting superb. In the question and answer session after the screening, Ms. Carter was asked if the split screen made acting more difficult. She replied that unlike the shooting of a "normal" movie where they would have to shoot each person's part separately then take a break and move the camera and do the other person, with both camera's running at the same time, the whole scene could be shot nearly continuously allowing for a more realistic conversation situation. This made things much easier, but she did admit she missed having any "down time" since she was always in front of one of the cameras.
