A peak behind the curtain into how long I’ve been writing this series. I started sketching thoughts on the Lucasfilm acquisition back in February, then started writing this article in April. I’m still finishing it in June. Fortunately, this extended timeline managed to teach me a rare lesson in humility about forecasting.
See, when I started writing, Solo: A Star Wars Story was still three months away. At the time, I needed to estimate for its box office performance to calculate the movie revenue. So I searched for projections. In early March, I found forecasts for Solo’s US opening north of $150-170 million, ending in a total US run of $350-$475 million. At the time, we all assumed Solo would be a sure thing at the box office. So I put that in my model. So I put into the model that Solo would do a bit less then Rogue One, at about $800 million in total worldwide box office.
By May, the estimates had lowered but still projected an opening weekend of $150-170 million. Days before the launch, the estimates had dropped even further, to $130-$150 million. The estimates continued to decay even as the weekend progressed, as this updated article from Deadline shows. Ultimately, Solo ended up with an opening weekend of $101 million domestic on track for about $350-360 million worldwide. (The March estimates had it at $350 for just the domestic market.)
Using the tracking data above, I see a “floor” domestically of about $300 million for Solo.
There’s a very famous quote about what people do and don’t know about movies. I won’t repeat it here, but I will agree that forecasting box office returns (and hence all revenue for a filmed project) is incredibly difficult. Even a movie as closely watched as Solo: A Star Wars Story missed most of the “ranges” offered by box office projections. My initial assumptions about Solo were way too confident which meant my entire analysis was off.
So we need to go into today’s post with a little humility and our eyes open. Last time, I asked a few questions:
Lucasfilm and Disney are doing well, but how well? More precisely, how much cash did they make on these movies? And how well do we think they will do going forward? Could they start losing money?
I answered the first two questions (doing really well; $3.7 billion in unadjusted gross profits or $2.5 billion in 2012 adjusted terms) in the last article. That was the easy stuff; what I called, “What we know” last time since I just had to plug the results into my model with some sleuthing.
Now comes the hard part. We have to estimate how future films will do and then guess about the rest of the potential slate. Which I’ll try to do this week. But first, I need to illustrate how hard this is…
Difficulty in Forecasting Box Office
To show the difficulty, let’s start with the difference between Solo: A Star Wars Story and The Force Awakens. One grossed $2 billion dollars at the worldwide box office. The other did under $400 million. That’s a gap of more than $1.5 billion dollars. That gap also roughly equates to how how large our confidence interval could be when projecting box office for films that aren’t coming out for two years (or longer). To capture that, look at this chart I made (using approximate numbers):
I put in these numbers as placeholder estimates. What they are are the fictional “90% confidence interval” for The Force Awakens. In other words, at greenlight, you could have guessed that a new Star Wars movie would do $2.4 billion in total box office or $400 million, and you’d be right, 90% of the time.
If that seems huge, it is. Projecting box office is tremendously uncertain and hence inaccurate. The internet and its data has improved the process, but only by about 4 to 8 weeks, not months out from release. But, again, as Solo: A Star Wars Story showed, this too can be off. As I’ve said before, this is why you can’t use data to predict how well movies will do. If it’s hard predicting a movie that has already been made, like Solo, it’s even harder when it is just an idea or script.
As we look towards the future of Lucasfilm, I want to acknowledge this. I’m not saying I can say, “Hey this movie will gross $X million dollars,” because frankly that’s nearly impossible. Instead, I need some analytical tools to get an approximate performance for all these films in total. The tools I will work with are using “comparables” to determine the range of outcomes and then “scenario modeling” to account for those ranges of outcomes.
Using a “Comparables Approach”
We’ll start with the “comparables approach” to box office forecasting.
I hinted above at a famous quote about “knowing things” when it comes to movies. I’m still not going to repeat it here, but the implication of the quote is I should give up now. If nobody can reliably forecast box office outcomes, it seems like it would be pointless to even try to make a model predicting future Star Wars films performance.
But just because we can’t forecast box office with tremendous precisions doesn’t mean we know nothing about box office. While we can’t forecast with 100% accuracy, we do know something: these movies are blockbusters. Moreover, they’re Star Wars films. We can use both of these facts to inform our predictions of how well these movies could do.
The best way to categorize this is the difference between a film’s box office floor and its box office ceiling. Blockbusters—like Harry Potter or Lord of the Rings or Marvel or DC or Star Wars films—have a peak ceiling in the billions. Small independent art house films have a very rare ceiling in the hundreds of millions. Different types of films also have different floors. May art house films have a literal floor of zero dollars. They get made, don’t find distribution and lose all their production money. Blockbusters can usually put up something of an opening weekend and make some money, but they just lose a whole lot more when they completely flop. (I’m looking at you, John Carter of Mars and The Lone Ranger. I wonder what studio made those?)
We know that future Star Wars films aren’t like horror films or serious dramas or raunchy comedies. They’re like other blockbusters. Knowing these are blockbusters, we can make a list of other blockbusters franchise films and see how well they did. Moreover, we can refine our list to comparable films that are in the same league as Star Wars, or trying to be. And even further, we can only include major franchises that released films recently.
So that’s a “comparables approach”. We make a list of films who most resemble the film we’re greenlighting. (Or films in this case.) We are careful to include both successful and unsuccessful films to know the true frequency of their occurrence. Then we analyze how well they did domestically and internationally. Then we create forecasts based off that data.
The Economics of Franchise Blockbusters
To start, we need our data. I made a data set of blockbuster franchises: Star Wars, Marvel Cinematic Universe, Harry Potter, Indiana Jones, DC Cinematic Universe, X-Men (Fox), Pirates of the Caribbean and Transformers. (Notable omissions: Jurassic Park, Star Trek, Fast and Furious, and James Bond.) Six franchises dating back to 1977 through 2018, encompassing 74 films.

Unfortunately, adjusted gross is only available for the domestic market. I still pulled unadjusted worldwide box office where it was available.
So we have our data. First, I wanted to see how Star Wars as a franchise performs. I pulled out the adjusted domestic grosses for each of the three Star Wars trilogies (Originals, Prequels, Current Star Wars) and an interesting pattern emerges. Take a look.
Those two charts are just the warm up. One franchise isn’t really a data set; a comparable approach with just one franchise is too small. Let’s see how all our franchises have performed over time.
They don’t. Still, let’s zoom in since only the MCU went over 11 films. Here’s the first 8 films in my data set:
Using a “Comparables Approach”: Creating our Comps
So let’s turn general performance into specifics. To make our “comparables” range, I made a new chart and table, but trimmed the date range. Going back to 1977 seems like too much. Adjusted gross starts to get wonky going back that far because so many variables change. So I kept my sample size back from 2008 to 2018. Do I have some great justification for starting at 2008? No. But I ended up with this cool chart where I put the franchises by name by year the film was released. Starting from 2008 drops our sample size from 74 films down to an even 50 for this section. But again, I just thought this looked really cool as a visualization:

To show that in numerical terms, here’s a count of each film by adjusted domestic box office
Models plural. I usually make three levels for a comparable model: hit, medium and flop. At greenlight, I’d usually include a “break even” to show what you need to make the money back. For this model, I’m going to add a fourth level on top: super-hits.
Super-hits are the ultra rare films that go well beyond most other films. I’d put Jurassic Park, Titanic, Avatar, Star Wars and three MCU films in this category. For my model, in box office terms, this means $700 million in domestic and $700 million in international box office.
Next, I made a “high”, “middle” and “flop” categories. High is $500 million domestic gross. Middle range is $300 million domestic gross, right between the band of $200-400 million. Any franchise film that can’t break $200 million in domestic gross I disparagingly call a “flop”, though it does mean the film will likely lose money. Normally, I’d need to model the international growth too, but Star Wars has helped me out there. Ultimately, Star Wars films have a much more even split than other franchises like Transformers or Lord of The Rings.


So that’s our “comparables” model. Essentially, in the world of “franchise blockbusters”—a category different than “blockbusters”—we have four categories of performance and we know how frequently they happen. But to build that business model, well, we need our “scenario modeling” which will happen tomorrow.
