There’s a shot in Downton Abbey: The Grand Finale, the third feature based on the popular TV series, that sums up the affection that fans have for the Crawley family and their estate. It’s a helicopter shot following a roadster as it drives important characters through the English countryside. The camera pivots slowly, tracking screen right, away from the motorcar. You know from a lifetime of movie-watching that it’s about to reveal the house. But the movie makes you wait and wait. Finally, there it is: the house where all of the drama has unfolded ever since Julian Fellowes’ series debuted in 2010.

It’s not a long moment, but it makes an impact. The film confidently cashes out the considerable emotional capital that the series has accrued. This is a story about people trying to avoid having to take a last look at Downton Abbey before moving on. It’s 1930, a year after a stock market crash that threw the world into an economic tailspin. The Crawley family has had to tighten its belt – as they’ve done periodically over the timespan of the show, which starts in 1920 – but not so much that they’ve given up their staff of servants and their assorted holdings, which include Dower House, former residence of Violet Crawley, Dowager Countess of Grantham (the late Maggie Smith, honoured with a dedication as well as oil painting of the countess looming over the front hall).

The low-level anxiety cranks up when the family is visited by American businessman Harold Levinson (Paul Giamatti), brother of Cora Crowley (Elizabeth McGovern). He’s brought another American, Gus Sambrook (Alessandro Nivola), a financier who, Harold says, helped keep the matriarch’s side of the family solvent after the crash. Unfortunately, Gus made bad decisions after that, depleting the nest egg that the Crowleys thought they could break open to renovate Downton Abbey and turn it into a rental property that could generate future income. Gus says he has a plan to take any funds that the extended family can scrape together and put them into high-risk/high-reward investments that will get them out of the hole that he and Harold put them in. Not everyone is on board with this.

At the same time, Lady Mary is getting a divorce, the news ripples through the surrounding community, making her a pariah among the high society people she used to call friends (even though they really weren’t). Some levity is added by actor Guy Dexter (Dominic West, totally believable as a Clark Gable-style movie star), who was at the center of the last movie. Dexter is reintroduced as the star of a London play by Noël Coward (Arty Froushan, who is absolutely credible playing one of the most charming men who ever lived). The family, sans Mary, is in attendance and goes backstage to meet with Guy, Coward, and Thomas Barrow (Robert James Collier), who is Guy’s assistant.

Dexter, Coward, and Barrow’s presence at Downton Abbey provides the movie with some of its more magical moments, the best of which finds Coward accepting a request to perform (he never says no) and singing to the extended family. Curtis lets the performance play out at length. Here, as in the show’s better moments, we get a sense of what constituted entertainment in an era when mechanical reproduction of images and sounds still seemed new, and people had to pay attention to things and be open to whatever they made them feel. What many of the characters are feeling, though, is dread of what’s next, and discomfort with the present.

The Finale is probably the tightest of the three movies, though also the most businesslike in its distribution of moments and subplots. Fellowes knows these characters so well that he can pack a lot into a brief exchange. Some of the most important business in the movie is resolved in a scene that might last a minute and have as few as four lines. This is very much an “old movie” way of telling an ensemble story, and Fellowes and Curtis are quite good at it, after all this time, though one might sometimes wish that they’d loosened their belts a bit and let the film run longer, since the viewer is deeply invested already, and wouldn’t mind lingering a tad, here and there.

This is the kind of movie where the whole point is to wonder what’s going to happen next and how it will affect the story, and it is told in such a way that what happens is invariably going to mean more to the audience than what it “means” in some larger sense. Downton Abbey has always been too sentimental about the rich and the royal during an age when the most privileged people in Great Britain lived that way because of inherited wealth and money built up from centuries of imperial plunder – something the dialogue on the show addressed, but only occasionally, and with obvious reluctance, because it breaks the spell cast by the sumptuous costumes and great halls and coaches and cars, and the items of furniture that probably have more market value than most people’s entire net worth. The main appeal here is the chance to spend time in the company of superb actors who all wear their characters as comfortably as an old silk robe.
