Michael Corleone begins outside his family's criminal power structure, but attacks on the Corleones pull him into revenge, succession, and the role of new Don.
The book and film trace the same family succession, but the film The Godfather narrows the book The Godfather around Michael Corleone's rise. That compression changes the pace, emphasis, and force of the final door closing on Kay.
PlotGeeks note
Removing several novel subplots does more than shorten the story. It makes Michael's decisions feel like the inevitable center of a family system, giving the film a cleaner and colder transformation.

How the novel becomes a tighter family tragedy
Michael replaces the novel's wider network as the center
The novel has room for more family business, history, and side stories. The film removes much of that material so Michael's change from reluctant outsider to Don becomes the clearest line.[1][2]
Explanation becomes ritual, silence, and parallel action
Puzo can explain how the Corleone organization works. The film lets weddings, office meetings, the baptism, and the closing door show how family loyalty and criminal power become inseparable.[1][2]
