Since I don't know the specific story, some possible key elements could be Anton Yelchin's journey in New York. If he started his acting career there, the early days of his struggle and success in the city could be a key part. The cultural aspect of New York would also be important. Maybe he was involved in some unique cultural events that are part of the story. And of course, his emotions towards the city, the love he had for it. It could be expressed through his experiences in different seasons, or his interactions with the diverse population of New York. Also, any projects he worked on in New York that had a significant impact on him.
I'm not fully aware of the exact story, but one key element could be Anton Yelchin himself. His talent, his charm, and his perspective on New York would be important. Another key element might be the locations in New York that are mentioned, like certain neighborhoods or landmarks. Also, any relationships he had in the city, whether with friends, colleagues, or other people in the film or art scene in New York.
