People always think of Waterworld or even Ishtar when they think of some of the biggest box office bombs of all time..but actually Waterworld cost a bloated $175M to make (in 1995 dollars no less), but at least grossed $264M worldwide. Considering all the marketing money they surely paid it still lost money, but nowhere near the scope of 47 Ronin, which also cost $175M to make yet made about $150M worldwide.
So clearly 47 Ronin lost money, a lot of money in fact...but nowhere near the worst flop of all time.
Whose idea was it for the word "Lisp" to have an "S" in it?
I think people confuse the reputation's of Waterworld and The Postman. The latter only took about $30m on an $80m budget.
John Carter is similar to Waterworld. Terrible rep and people think it was a financial disaster, but it actually grossed $284m on a $250m budget. Obviously the marketing costs were huge though, so it made a big loss.
Wikipedia have a good page on movie bombs, they seem to incorporate (presumably estimated) marketing costs into the production budget. As a result they price 47 Ronin at $225m, which sounds about right to me. $50m isn't that much for marketing of a big release, but it didn't get much marketing.
For what it's worth, this is the Wikipedia 'top' 5 with estimated loss in brackets:
1. 47 Ronin ($149,518,763) 2. Mars Needs Moms ($130,503,621) 3. The 13th Warrior ($69,150,551—129,150,551) 4. John Carter ($121,630,450) 5. The Lone Ranger ($94,748,943—119,748,943)
For what it's worth, this is the Wikipedia 'top' 5 with estimated loss in brackets:
4. John Carter ($121,630,450)
Which is way off target. John Carter's budget was $306.6m (verified by the UK treasury, who publish final budgets of all films eligible for UK tax breaks), and its marketing costs another $100m on top of that. Before it finished its theatrical run, Disney announced to investors a minimum $200m loss on the film (based on a higher closing gross than it actually achieved), the highest ever recorded.
By comparison, 47 Ronin cost $130m less and had a much smaller marketing spend because Universal basically dumped the film. It's pretty clear what the bigger money loser was of the two. But then Wiki also has the $85-90m budgeted The 13th Warrior costing $160m to make it appear an even bigger flop than it was.
