They have a stated budget of $250 million. That is not how much it ACTUALLY costs, that is how much they THOUGHT it would cost before production took place. Consider $250 million to be the LEAST they spent.
Then there is marketing. For comparison, The Dark Knight Rises had a $100 million marketing budget in 2012. That would be about $150 million adjusted for inflation. $250 plus $150 equals $400 million.
The rule of thumb has break even being double the cost of production plus marketing. That would put break even in the ballpark of $800 million.
Since this was filmed in the UK for the tax credits, we will eventually get the actual production costs. I will bet you $100 right here and now that when that cost is revealed, it will be in excess of $250 million.
