James Norton in Grantchester: Reasons why he left explored

Sidney’s story reached a natural end

In the third season of the series, Sidney faced the main troubles that shaped his character. He balanced life as a vicar with personal feelings about love. The long romance with Amanda came to a firm end in that season, and Sidney then made a clear choice to focus on the church. Norton felt this change closed the most urgent chapters of Sidney’s life.

The deeper inner struggles that drove his actions were resolved, and the character no longer had the same urgent questions to explore. Norton and the producers agreed that stretching Sidney into a new, large storyline would feel forced. He wanted an honest ending, and the story they filmed felt true to the character. Leaving at that point let the role rest with dignity, and it let the series find a new direction without weakening its core.

A wish for new roles and new faces

While filming Grantchester, Norton was also appearing in other notable projects. He had roles in shows like War & Peace and McMafia. These parts gave him a wider range of acting experience, and he wanted more variety.

Norton spoke about exploring different characters and testing himself in new scenes. He saw leaving as a way to grow professionally and to accept fresh creative challenges.

The choice also opened a chance for the show to bring in new energy. Tom Brittney joined the cast as Reverend Will Davenport, and his arrival gave the series a new focus. The transition let Grantchester keep its setting and tone, while offering audiences different stories to follow.

A genuine, emotional goodbye

Norton left early in the fourth season, and his final scenes carried real emotion. On screen, Sidney and Geordie shared a farewell that felt honest and quiet. Off-screen, Norton and Robson Green, who plays Geordie, had a warm friendship, and that bond made the farewell powerful.

Norton has joked about dramatic exits, like Sidney becoming the victim of a major crime, yet the writers chose a subtler path. The quiet goodbye showed Sidney’s inner decision, and it matched the character’s temperament. Viewers reacted strongly, and many said the exit felt respectful to the time the character had spent on screen.

What did the change mean for the show?

The departure let Grantchester evolve without losing its core appeal. The village, the crimes, and the bonds between characters remained central. At the same time, a new lead brought fresh problems and fresh chemistry.

This balance helped the series keep existing fans and attract new ones. For Norton, leaving created space to take on varied roles. For the producers, the change allowed the show to explore new stories without repeating old patterns.
