The 30 most expensive movies ever made

As the box-office returns for Hollywood blockbusters continue to break records, so do the budgets to make and market them. 

With Warner Bros.' highly anticipated "Batman v Superman: Dawn of Justice" opening Friday, rumors are that it's the most expensive movie of all time, with a supposed $410 million price tag (though that might also include the cost to market it).

While the studio is staying mum about the movie's cost, given how budgets have ballooned over the decades, it's not long before $300 million to 400 million production budgets become the norm for blockbusters.

To look at the evolution, we turned to IMDb and Box Office Mojo to gather the 30 priciest films ever made, and we consulted the consumer price index to adjust for inflation. 

We've also included the movies' estimated original budgets and box-office revenue for comparison.

Let's find out if spending all that dough was worth it.

Note: Numbers in the titles are adjusted for inflation, while original budgets are below.
