This holds true for books, too. However, the Economist recently published a 10-year study on movies that analysed the performance of over 2,000 films to see which factors help make a movie a hit.
The results show that there is much a movie studio can do to help a movie become a box office hit. Interestingly for us, most of that can also be applied to books, to help ensure their success.
Even if it got no boost from its cast, from favourable reviews or other factors, a movie would generate an average of 80 cents at American and Canadian cinemas for every dollar a studio promises to spend on it.
The more a studio commits to producing a film, the more it is likely to spend on advertising it. The budget also helps determine how widely a film is shown.
Sequels & Franchise: Child-Friendly Superheroes
Sequels and franchise films are another way for studios to limit their risks. Nearly one in five of the films nowadays is a sequel, up from one in 12 a couple of decades ago. All other things being equal, sequels earn $35m more than non-sequels at the box office.
Franchise films increasingly depend on superhero characters. Hollywood made just eight superhero films between 1996 and 2000, but 19 in the past five years. A $200m-budget superhero film will earn $58m more at the box-office than a non-superhero film of the same budget.
Superhero films (“Deadpool” excepted) tend to be child-friendly, for good reason: films that receive an “R” (restricted) certificate typically earn $16m less in cinemas.
Everyone’s a Critic
Do critics play a role in the success of films? Not as much as they would like to think. Between 1996 and 2006 an extra ten percentage points on the aggregate critics’ score on Rotten Tomatoes was associated with just $4m in extra box-office takings. Now it is worth just $1m.
The wisdom of crowds matters more these days: the same increase in positive audience reviews on Rotten Tomatoes is associated with an $11.5m increase in box-office revenues.
Taken together, these factors explain about 60% of the variation in box-office revenues. Adding an estimate of marketing costs increases the model’s accuracy by another 20 percentage points.
The Economist’s analysis suggests a formula that maximises the chances of packing them in – in movies and, I believe, in books:
- Have a budget that will allow your book to be as professional as possible.
- Create a child-friendly superhero film with plenty of action and scope for turning it into a franchise.
- Advertise and promote widely.
- Distribute it as widely as possible, and in the summer (when releases earn films an average of $15m more than at other times).
With reasonable reviews from the audience, your book should be a success. But do it for the money, not the plaudits: such a film would have just a one-in-500 chance of carrying off an Oscar for Best Picture.
