Definitely. The filmmakers drew from true stories to create the framework of Manchester by the Sea. This infusion of reality adds depth and poignancy to the film's plot and characters.
One of the most prominent aspects from the true story in 'Manchester by the Sea' is the main character's inability to move on from his past. This is shown through his interactions with the town and his family. The real - life story must have had some deep - seated traumas that the movie translates into the character's hesitance to take on new responsibilities, such as caring for his nephew. Another aspect is the small - town atmosphere and the sense of community. In a small town, news travels fast, and people are often intertwined in each other's lives, which is clearly depicted in the movie. This is likely based on the true - story elements of how the real - life town functioned and how the people in it related to one another.
