Shawn Ku said that although Bill and Kate have been married for 20 years in the film, they still don't know each other. Therefore, the performances directed by Maria Bello and Michael Christopher Sheen focused on shaping the relationship between the characters. Shawn Ku did not emphasize the lines and position in the directing and rehearsal, but emphasized the expression of the relationship between the appearance of such characters. Because the filming cycle is very short and the time is tight, it is extremely necessary for the actors to enter the state as soon as they enter the crew. So he spent a lot of time in the early stage of filming explaining basic issues such as roles, personality, relationships, etc. When these basic problems are solved, the lines, performances, and positioning will be a matter of course. Shawn Ku hopes that what they can show is a kind of authenticity, originality and delicacy in life, which is also his requirement for scripts and films.
Visually, Shawn Ku requires the film to be very ordinary and very simple, and shoot whatever the eye sees. It is necessary to achieve a "primitive sense" of "naturally carved". In terms of specific implementation, Shawn Ku and photographer Michael Femugnari chose highly mobile handheld photography, and adopted a large number of photographic techniques with documentary aesthetics, such as follow-up, long lens, and rotation. Shawn Ku said that in order to achieve this goal, the crew made a lot of attempts and preparations. Shawn Ku let the protagonist choose their own position and location in the room, so that the film has a sense of emergency. Then he let the photographer in and waited for the opportunity to shoot. Because in a documentary, everything will not happen a second time, only God is the director. So Shawn Ku asked Michael Femugnari to use the camera as much as possible to capture what's happening indoors. The goal is to take care of every corner and every detail in a shot as much as possible, and shoot a kind of ordinary, simple and documentary shot.
In order to achieve this goal, Shawn Ku gave Michael Femugenari an extremely relaxed working environment. He asked Michael Femugenari to design his own shooting method, design the lens position, and feel his own shooting style. Shawn Ku said that the film's photography has fulfilled his expectations very well
