Previous budget reports said the movie cost $250 million to produce. The actual budget, per this report at Forbes, was $300 million, which does not include promotion costs.

The only reason we know the truth is because Disney wanted tax credits from the United Kingdom, where much of the movie was filmed, and the UK doesn’t put up with bookkeeping shenanigans the way we do here in America.

In the U.S., studios can and do lie about budgets all day long. First, they lie about the movie costing less than it actually did so it looks like a hit. Then the studios lie about it costing more than it actually did so they don’t have to pay out that backend money.
