Quentin Tarantino has officially shelved his next project, The Hateful Eight. The director made the decision after the film's script leaked a few days ago, and as you can expect, QT enthusiasts aren't happy. In addition to having obvious parts for two of my favorite actors -- Christoph Waltz and Bruce Dern --The Hateful Eight was supposed to be a sprawling, epic Western with all the violence and extended dialogue of a typical Tarantino movie.

Besides the fans, there's another group of people who are likely disappointed by this news: movie studio executives.


The Tarantino take
Because the average Quentin Tarantino movie does extremely well at the box office.

Quentin Tarantino's Directorial Career, Full-Length Films
Film* Year Box Office Budget ROI
Django Unchained 2012 $425M $100M 325%
Inglourious Basterds 2009 $321M $70M 359%
Death Proof (Grindhouse) 2007 $25M $67M -62%
Kill Bill: Vol. 2 2004 $152M $30M 407%

Reservoir Dogs 1992 $14M $1.2M 1,122%

He's directed a total of eight full-length films in his career, and only one -- Death Proof, part of the Grindhouse double-feature -- failed to make at least four times its initial budget.

Considering Hollywood's typical return on investment per movie is between 30% and 40%, it's remarkable that Tarantino's films generate such lofty profitability figures. The reason is simple: Most of his projects don't require expensive special effects or set pieces, and thus, they require less studio money than the average summer blockbuster.

The fact that his budget has increased with every new project since Reservoir Dogs is a testament to Tarantino's ability to make profitable movies, but even his most expensive -- Django Unchained -- was still a few million dollars cheaper than the average MPAA-rated film.

Put simply, QT is an executive's dream. So how much money might The Hateful Eight have made if it was released next year as originally planned?

This is a tougher question to answer.

The modern Western
Although Django Unchained was the world's highest-grossing Western ever, the genre is littered with commercial letdowns like 3:10 to Yuma and Seraphim Falls.

Judging by the low number of films produced in this style, studios have largely avoided the risk of a flop in recent years.

Movie Production By Genre, 1995-2013
Genre Movies Produced Box Office Take Per Movie (U.S.)
Adventure 768 $54M
Action 1,032 $36M
Thriller/Suspense 895 $20M
Western 94 $20M
Romantic Comedy 525 $19M
Comedy 2,834 $19M
Musical 195 $19M
Horror 588 $17M
Black Comedy 131 $9M
Drama 4,364 $8M

Documentary 1,387 $1M

One thing still intrigues me though: Westerns take in more money than Romantic Comedy, Musical, Horror, and even Drama films on average. To understand why, think of the movie industry as an interaction between supply and demand.

The economics
Fans demand movies, and in turn, movie producers supply them. Certain genres are currently in high demand, such as Action films, so studios supply a lot of them. Others, like Westerns and Musicals, are in lower demand, so studios produce fewer of those.

As is the case in any supply-demand relationship, the price explains exactly where both sides -- fans and studios in this case -- are interacting. Because the average box office take of Westerns is significantly higher than other low-demand genres, it theoretically implies that there's a shortage of this kind of movie, i.e. there's a lack of supply.

If there weren't a lack of Westerns, they wouldn't take in more money than Comedies and Dramas, which are far more popular.

It stands to reason, then, that Hollywood is ripe for another Western to follow in the footsteps of Django Unchained, and interestingly enough, the last five with budgets over $100 million have done fairly well.

The Lone Ranger 2013 $260M $215M 21%
Django Unchained 2012 $425M $100M 325%
Cowboys & Aliens 2011 $174M $163M 7%
Rango 2011 $245M $135M 82%
Wild Wild West 1999 $222M $170M 31%

The estimate
With that in mind, a reasonable box office estimate for The Hateful Eight would take the average ROI of Tarantino's films, and the average ROI of the past five big-budget Westerns: This comes to 477%.

Assuming a 477% return on a $125 million budget -- a modest increase from Django Unchained -- that equates to a profit of almost $600 million, and a total box office take of more than $700 million. Of course, that would make The Hateful Eight the new highest-grossing Western of all-time, which isn't as crazy as it sounds considering Tarantino's last project.

Given a budget of at least $100 million, the The Hateful Eight would still be one of the top-grossing Westerns in history if it simply matched the profitability of less successful films like The Lone Ranger and Wild Wild West, both of which had ROIs near the industry norm.

This may represent a worst-case scenario, but as long as Tarantino avoids Will Smith-esque one-liners, this shouldn't be a problem.

The future
It was never released which studio was being considered to work with the now defunct movie, but if recent history is any suggestion, Tarantino may have gone with Sony's (SONY 2.58%) Columbia or Comcast's (CMCSA -0.12%) Universal; each had a hand in his last two films. The privately held Weinstein Company would have likely been involved in distribution.

As for now, the director has said he will turn The Hateful Eight into a novel and move onto another project. Candidates for his next film include: Killer Crow, a revenge-themed WWII film; Faster Pussycat! Kill! Kill!, which follows killer go-go dancers; a sequel to Pulp Fiction; or according to The Wrap, "a prison movie of sorts."

No matter what Tarantino decides to make, there's little doubt it will do well at the box office. Judging by the apparent shortage of Westerns, though, and the fact that every recent big-budget film in this genre has been profitable, he may want to reconsider if The Hateful Eight should really be canned. 

At the very least, QT, I'd recommend you sleep on the decision for a few weeks.
