To be clear, this is the Mahershala Ali clone movie Swan Song (2021) directed by Benjamin Cleary, not the Udo Kier hairdresser movie Swan Song (2021) directed by Todd Stephens. That movie is on DTDD at doesthedogdie.com/media/846842
There is no physical violence shown. At one point near the middle of the movie, the main character dreams of his clone becoming angry with his family and throwing an object at a wall.
Child birth is not shown - there is a scene shown in a hospital, after the main character’s spouse has given birth. She is shown holding the baby while smiling, seated in a hospital bed wearing a hospital gown, with the main character, who is also smiling.
central theme of the movie - referenced in passing several times, treatment decisions and doctor interaction and effect on family is a central focus of the movie. A person is shown to have scarring on their face and they are shown laying down in a bed ill with nose tubes. (Spoiler) Their death is implied (not shown).
Several scenes take place in a train car. The car is not shown to be cramped or crowded (several people on the car, when leaving the car people appear easily able to move - I don’t recall any claustrophobia related space interactions)
In a remembering sequence the main character’s spouse is shown in a hospital bed holding a baby, the main character next to them. Their expressions are happy and sequence lasts for several seconds.
(Potential spoiler) The main character is under medical duress and the doctor violates his last expressed wish by making a choice for him and bringing him back to the lab when he is unconscious (in their last conversation he had firmly and openly expressed his intent to not return and to not move forward with the treatment).
If a viewer is sensitive to this topic, they may find the interaction of the main character and his clone activating. The clone is shown with their eyes closed prior to coming awake, and there is frequent interaction between the main character and their clone for a large part of the movie (including when their clone returns back to the main character’s home)
