Most films do lose money in theaters. It's like the game industry, you use the few big hits to finance the rest.
And once again, you have the other revenue streams outside of the theater to help out, and hopefully put you in the black.
I don't know if that's true. I go back to Fox/Sony deal with Marvel (in part because those old Marvel deals are fascinating to me). Unless my math is incorrect and using the formula, we get:
XMenA: Budget 178M, BO: 541M. Loss of -85.5M
Deadpool: Budget 58M, BO: 783M. Profit of 275.5M
XMenDOFP: Budget 200M, BO: 748M. Loss of 26M
The Woverine: Budget 120M, BO 415M. Loss of 32.5M
XMen First Class: Budget 140 -160M, BO 354M. Loss of 103 - 143M
XMen Origins Wolverine: Budget 150M, BO 373M. Loss of 113.5M
XMen Last Stand: Budget 210M, BO 460M. Loss of 180M
X2: Budget 110M, BO 408M. Loss of 16M
XMen: Budget 75M, BO 296M. Loss of 2M
FF: Budget 100M, BO 331M. Loss of 34.5M
FF Rise of Silver Surfer: Budget 130M, BO 289M. Loss of 115.5M
Fan4stic: Budget 120M, BO 168M. Loss of 156M
Fox would still have to pay Marvel a fee on all those BO gross, so a bigger loss/smaller profit. Only 1 profitable movie in 16 years. Negligible to no merchandise revenue/profit. VOD, TV licensing, Blu Ray, DVD revenue/profits are all shared.
Spiderman: Budget 139M, BO 822M. Profit of 133M
Spiderman 2: Budget 200M, BO 784M. Loss of 8M
Spiderman 3: Budget 258M, BO 891M. Loss of 70.5M
Amazing spiderman: Budget 230M, BO 758M. Profit of 19M
Amazing Spiderman 2: Budget 200-293M, BO 709M. Loss of 45.5 - 231.5M
Up until 2011, Sony had to pay Marvel a fee of the BO gross and got a percentage of the merchandise deal, after that they pay no fee for the BO gross and don't get a percentage of any Spiderman merchandise. That started with Amazing Spiderman.
2 profitable movies, one possible huge loss. No merchandise revenue/profit. VOD, TV licensing, Blu Ray, DVD revenue/profits are all shared.
Looking at the numbers above, and considering that Fox and Sony would only make money off DVD/Blu Ray/VOD sales (and still have to pay a fee on each item sold), it seems like a loss venture for them and not worth it. Why would they keep pumping out movies that they are constantly losing millions on? These people didn't get rich by throwing money away.
Of course I don't think that is the case as Fox even went out of their way to rush a Fantastic Four into production just so they could keep the license.
Sorry about the formatting, did it in a hurry.
