Whoever updated the wiki site information missed some movies (and details).
thenumbers.com: Movie Budget and Financial Performance Records
I think this website is wrong. I bet they are mixing production numbers and production + marketing numbers. Box Office Mojo and the Wiki show the Lone Ranger production budget as $215 and $225 respectively with the wiki claiming the $225 number is confirmed. Maybe the extra $50 million that is reported on the-numbers.com is marketing for that movie?
Nope, the estimated marketing cost for the Lone Ranger is $150 million worldwide. Astonishing! Assuming Avengers AoU had a similar marketing cost, they movie better make well more than $1 billion dollars.
The three movie analytic sites try to report on just the production budget, though boxoffice.com started plugging in an estimate of marketing expenses a few years back.
Avengers: Age of Ultron
thenumbers.com (production budget): $250,000,000
boxofficemojo: $250,000,000
boxoffice.com: $340,000,000 (*)
* BoxOffice.com's total budget numbers are a combination of production budget figures and estimated domestic P&A costs
I would assume boxoffice.com is plugging in the $250 MM plus Print & Advertising expenses.
I'm just guessing (if Batman & Robin can almost make a billion-the DVD commentary), they'll probably pull in a couple billion or more for the next year in merchandising. I'm still seeing a lot of licensed Avengers 2 stuff out there (a lot of back to school stuff and costumes, toys and the Blu is out Oct.4). I'm still seeing Iron Man 3 and Avengers #1 stuff in discount stores.
