Why do movies cost so much to make?

Before we break down movie budgets, we should emphasize that Hollywood accounting is fishy at best. Studio heads always low-ball the cost of their movies to make them appear more profitable while inside sources cite exorbitant unreported costs. The safe bet? Assume everyone is lying [source: Goldstein].

Even though specific numbers are hard to nail down, we have a good idea where studios spend their money. A film's production budget includes all costs incurred during pre-production, filming, post-production and promotion. That includes buying the rights to the script, actor's salaries, production staff salaries, set construction, special effects, wardrobe, craft services, marketing, dog training -- everything! How much does "everything" cost? The average production budget of a major studio film in 2007 was $106 million [source: MPAA].

Marketing makes up a huge chunk of modern movie budgets -- $35.9 million on average -- largely because the fates of many Hollywood releases are sealed in the first week. Big money is spent on trailers, TV ads, billboards, and Web sites to pack people in on opening weekend. That strategy seems to work: "Spiderman 3" made 45 percent of its total gross ticket sales in its opening week, while "X-Men: The Last Stand" made 52 percent of its money in its first week of release [source: Box Office Guru]

When calculating a marketing budget, the rule of thumb is to spend 50 percent of the rest of the production costs (pre-production, filming and post-production) [source: Vogel]. So if a movie costs $100 million to make, you'll need an additional $50 million to sell it.

For studio films, the traditional "safe bet" is to spend major money on a big-name actor. The rationale is simple: Stars sell more tickets and are more recognizable or marketable to international audiences. Once a star has a few mega-hits under his or her belt, they're usually welcomed into the exclusive $20 million per movie club -- although membership isn't a lifelong privilege.

After a series of relatively star-free hits like "Transformers," "Star Trek," and "The Hangover," -- plus a growing list of superstar flops like Will Farrell's "Land of the Lost" and Julia Roberts' "Duplicity" -- studios are starting to see the light [source: Dobuzinskis]. Icons like Denzel Washington and Tom Cruise are taking pay cuts up front in exchange for a bigger cut of DVD sales and distribution deals on the back end.

Not surprisingly, the most expensive movies of the past 20 years have had the biggest special effects budgets: "Spiderman 3" ($258 million), "Harry Potter and the Half-Blood Prince" ($250 million), and "Superman Returns" ($232 million) top the list [source: The Numbers]. For "Transformers 2" ($225 million), special effects powerhouse Industrial Light and Magic used 40 full-time animators [source: Tucker]. James Cameron, who more or less invented the super-budget special effects genre with "Titanic," developed his own 3D technology for "Avatar" -- and paid $14 million of his own money to do it [source: Cieply].

With all that money flying around, you'd think that studios could at least spot a potential hit. Not in the least. Every film is a unique product (even sequels) that enters an ever-changing market [source: Vogel]. The next big thing could be a low-budget comedy or a $250 million special effects extravaganza. You never know -- and that's entertainment!
