It seems that the cost of pitting two good guy superheroes against each other is far higher than any city-levelling showdown in history.
In fact, Batman V Superman: Dawn of Justice is costing around $410 million (£264 million).
That means it could be the first film ever to cost over half a billion dollars - and new behind the scenes pictures from Total Film showcase why the costs are skyrocketing faster than Superman's bullet-speed flybys.
The current record holder for most expensive film ever made is Pirates of the Caribbean: On Stranger Tides, which cost $410 million, which the new comic film will almost certainly edge.
But Batman V Superman may not hold the title for all that long. Rumour has it that Avengers: Infinity War has a budget of a billion dollars.
To be fair, the trailer looks brilliant, but even Bruce Wayne’s wallet would take a hit from that amount of cash.
