Set Design
The set design in the opening scene where Arthur’s sign is broken is a very effective introduction to the world of the movie and the life of Arthur. Having the only bright and joyous thing injured and broken on the ground sets the hopeless tone and themes of the film, and having him be surrounded by bags of trash conveys to the audience that Arthur is seen this way by the rest of the film’s world; no more than trash to be left on the streets.
Costume
The usage of the clown masks in the train scene, worn by most of the people on the train, demonstrate perfectly the unification of the poor of Gotham, now identifying with Arthur’s actions. However, Arthur still wears much brighter colours in this scene – it can be said that vibrancy in this film represents freedom from oppression, which is something Arthur now has much more of due to his complete rejection of society’s rules and laws.
Space
In the Wayne Manor scene, the usage of space and the lack thereof is highly effective. The incredible distance from the gates to the manor show just how far Arthur is from the life he could’ve had, and, though separated by the gates (demonstrating class divide), there is little space between him and Bruce, which contrasts the previous message by showing that they could’ve each been on either side of the gate were they born into each other’s worlds.
Lighting
The lighting in the comedy club scene is very uncomfortable and oppressive. It feels hot and disorienting. Coming from behind the audience, it also hides their reactions – playing into the audience’s questioning of how reliable the narrator really is. The lights are on Arthur, just like in his dream of appearing on the Murray Show, which fully feeds into his delusions of perceived value.
Composition
We see the stair dancing scene from a low angle, showing the entire set of stairs in the background as Arthur continues to dance down them. These stairs have repeatedly represented the rungs to the ladder of Arthur’s place in the world – but now, instead of struggling to climb, he dances down, and we can see how far he has fallen and are left doubting how much further he can go. The light is behind him now, and he has chosen to abandon it.
Hair and Make-up
The hair and makeup in the scene when Arthur’s two friends visit, before he kills one, is very heavy and realistic. It defies the common movie trope that someone’s plan and downfall goes uninterrupted, and the unfinished, blotchy makeup mixed with the still drying hair fully encapsulates finding someone as they are spiralling.
Film Stock and Aspect Ratio
Joker has an aspect ratio of 1.85:1, helping with it’s long shots, but making it necessary to use other things in the scene to block parts of the camera to create claustrophobic feelings.
