ZSJL didn't get released to theatres. Pretty sure that has been said about 100 times in the thread.
MoS 668m
BvS 872.7
SS 746.8
WW 822.8
777 million average and that was with a heavily messed with SS and 1/6 of BvS missing.
I undertand that it wasn't released in theaters, but JL was and WB looks at the whole end project budget which is ZSJL when it looks at the loss/profit. They have always done that. Example, the actual cost to make Star Trek the Motion Picture wasn't 35 million, it was less, but they add in all the money they spent on the failed TV reboot and all the money spent on all the previous scripts written.
I see you are using Suicide Squad instead of JL which is fine, but odd you leave out all the ZS movies in your numbers.
I'm using the numbers website to pull these.
Man of Steel production budget $225,000,000 (worldwide box office is 3.0 times production budget)
BvS production budget $263,000,000 (worldwide box office is 3.3 times production budget)
Wonder Woman production budget $150,000,000 (worldwide box office is 5.5 times production budget)
Suicide Squad production budget $175,000,000 (worldwide box office is 4.3 times production budget)
First thing that jumps out at me is you meant average per movie not overall, you didnt say that.
Second they did all make money but did they make enough for the Studio to want to continue making them?
I hate to use a MCU move but we are talking Super hero movies.
Ant Man production budget $130,000,000 (worldwide box office is 4.0 times production budget)
I chose Ant Man becuase he is probably the least known super hero to the general public, especially compared to Superman and Batman. As you can see Ant Man out performed both Zach Snyder directed films with two more popular heros, and was done on a smaller budget.
Which brings me to the third thing I noticed. The movies not directed by Snyder did better then the Snyder movies did. That's another important fact and is one that probably led to his eventual ouster.
Here;s another example you might dismiss because its a different genre, but I'm using it as a example how poorly the ZS movies actually did.
Pirates of the Caribbean on Stranger Tides Production budget $379,000,000 (worldwide box office is 2.8 times production budget)
POTC is the most expensive movie ever made and it made just a little less then MoS the 30th most expensive movie ever made and .6 less the BvS the 11th most expensive movie ever made. A movie that cost over 100 million more and that came from a smaller franchise and was by most accounts one of the worst of the series, almost performed better then the ZSDC movies.
Now lets look at the nail in the coffin.
Justice Leage production budget $300,000,000 (worldwide box office is 2.2 times production budget)
Justice League was the 6th most expensive movie ever made. It made less money then POTCST
In addition, we are seeing a trend here with Zach Snyder, his movies are getting more expensive, and giving less profit in return. Knowing what his plans are now for the sequels to JL as awesome as they sounded, they also were going to be even more expensive. MoS was the 30th most expensive, BvS was the 11th most expensive and now JL is the 6th most expensive that's a significant increase in cost per movie. Considering none of these have cracked the billion dollar mark, and the profits were trending downward, why would a studio want to invest more money in a project that didn't even have strong fan base. The movies were very divisive with the general audience vs the Marvel movies at the time which were making a billion each and was loved by the general audience.
Bottom line. DC wanted a Avengers like franchise with billion dollar movies. Zach Snyder had a good plan, but couldn't deliver the billion dollar movies. It's no surprise that the studio pulled the plug on them with the uptrend in cost and the downtrend in profit.
Just for fun I pulled the second most expensive movie ever made which happened to be a MCU movie
Avengers Age of Ulton production cost $365,000,000 (worldwide box office is 3.8 times production budget)
It outperformed both of ZS first DC films, and made over a billion dollars. That is what WB wanted, not what ZS gave them and from all evidence he would never be able to give them that. It also explains why the studio got so involved with JL messing the ZS plan up and eventually ousted him.
