Why the franchise won
Studios do not prefer franchises because audiences demanded them; they prefer them because a known property reduces the marketing problem. A new title has to explain itself in thirty seconds to a global audience across dozens of languages. A sequel only has to announce a date. Add international box office, where recognisable spectacle travels better than dialogue, and the incentive is overwhelming.
The cost is creative concentration. When a small number of properties absorb the available budget, the mid-budget adult drama that once trained directors and stars has fewer places to exist, and most of it has migrated to television and streaming, as covered on the screen icons page.
The trilogy that set the standard
Peter Jackson shot The Lord of the Rings in New Zealand as one continuous production, releasing The Fellowship of the Ring in 2001, The Two Towers in 2002 and The Return of the King in 2003. The last of the three won eleven Academy Awards at the 2004 ceremony. The lesson studios took from it was that audiences would commit to a multi-year story. The lesson they largely did not take was that it worked because the whole thing was written and shot before the first instalment was released.
Growing up in public
The Harry Potter films ran across eight releases from Philosopher's Stone in 2001 to Deathly Hallows – Part 2 in 2011, ageing their cast in something close to real time and darkening in tone as the readership did. That synchronisation between character age and audience age is very difficult to repeat deliberately, and the spin-off films set in the same world have had to solve a harder problem without it.
The Marvel model
The Marvel Cinematic Universe began with Iron Man in 2008 and the post-credits scene that promised something larger. Disney acquired Marvel Entertainment in 2009. The Avengers in 2012 proved the crossover could carry a film in its own right, and Avengers: Endgame in 2019 closed an arc assembled over more than twenty releases.
The structural innovation was the phase: a batch of films with individual plots and one shared thread, so that each entry functions as both product and trailer. The structural weakness appeared later. Once television series on Disney+ carried plot required for the films, the entry cost for a casual viewer rose sharply, and homework is a difficult thing to sell as entertainment.
Buying a galaxy
Disney acquired Lucasfilm in 2012 and released The Force Awakens in 2015. The sequel trilogy's changes of director and shifting continuity became a case study in what happens when a world is expanded on a fixed release calendar rather than a finished plan. The Mandalorian, launched with Disney+ in 2019, went the other way: a modest weekly serial in a familiar setting, which turned out to be a more comfortable fit for the material.
Comparing the structures
| World | Century entry point | Structural idea |
|---|---|---|
| The Lord of the Rings | The Fellowship of the Ring (2001) | Single production, three releases, fixed ending |
| Harry Potter | Philosopher's Stone (2001) | Adaptation in publication order, cast ages with audience |
| Marvel Cinematic Universe | Iron Man (2008) | Phases of standalone films sharing one thread |
| Star Wars under Disney | The Force Awakens (2015) | Legacy continuation plus streaming serials |
| Avatar | Avatar (2009) | Long gaps, technology-led event releases |
When it does not work
Universal announced a connected series of monster films and, after The Mummy in 2017, did not proceed with the plan as presented. DC's film universe has been restarted more than once. The pattern in the failures is consistent: the shared universe was declared before a single entry had earned an audience's affection, which is the equivalent of printing the sequel's poster before writing the first script.
The one-off that behaves like a franchise
Not every event film needs a universe. Avatar arrived in 2009 as a technological argument for the cinema itself, and Avatar: The Way of Water followed in 2022 after a gap long enough to be a joke in its own right. In July 2023, Barbie and Oppenheimer shared a release date, and the resulting double-bill enthusiasm did more for cinema attendance that summer than any amount of connected-universe planning — a reminder that the reliable driver is the sense of an occasion, not the continuity.
What makes a world durable
- A finished shape. Audiences will follow a long story if they believe it has an ending.
- A low entry cost. If a newcomer needs a viewing order diagram, growth has stopped.
- Design that survives merchandising. The silhouette on the lunchbox is doing real work.
- Room for a different tone. The worlds that last allow a comedy, a western or a small character piece inside the same setting.
