Warner Bros.' Batman v Superman: Dawn of Justice represents the first time iconic superheroes Batman (Ben Affleck) and Superman (Henry Cavill) will be seen on the big screen together, when it hits theaters next March. This massive comic book adventure could end up making history in a completely different way, if a report from Latino Review is accurate. The site's sources claim that the budget has gotten so out of control it may be the most expensive movie ever made.

The report claims that Warner Bros. has spent a whopping $410 million, which, if accurate, would put it incredibly close to breaking the record of $410.6 million, spent by Disney on 2011's Pirates of the Caribbean: On Stranger Tides, according to financial documents obtained by Forbes. Before that movie went into production, Pirates of the Caribbean: Dead Man's Chest had the record with $341.8 million, followed by Cleopatra, which cost $44 million to produce in 1963, which comes out to $339.5 million when adjusted for inflation.

As of now, Warner Bros.' hasn't confirmed how much they have spent on Batman v Superman: Dawn of Justice, and it isn't known why exactly so much was spent, but the site claims that, "the addition of big name cast members, practical sets, and an extended production schedule could have all contributed" to the massive budget. This news comes just a few days after another unverified report claimed that Marvel may be spending a cool $1 billion on both Avengers: Infinity War Part I and Avengers: Infinity War - Part II combined. Warner Bros. is also mounting their own two-part superhero movie, Justice League Part 1 and Justice League Part 2, with sources claiming the studio plans to spend $500 million on both movies combined. Director Zack Snyder and his team are currently prepping for a 16-month shoot in London, which includes pre-production and principal photography.

Batman v Superman: Dawn of Justice, and the massive slate of films that will follow it, have often been described as dark and gritty, which will be a stark contrast to the Marvel Cinematic Universe, especially since Kevin Feige has stated in the past that the MCU will never go "dark." We have also heard Batman v Superman: Dawn of Justice described as "grounded" in reality before, which was reiterated by cast member Scoot McNairy, whose mysterious role still hasn't been revealed yet. While promoting his new film Our Brand Is Crisis, in theaters next weekend, the actor had this to say about Batman v Superman: Dawn of Justice.

"This is the superhero film that is more grounded in reality than any of the other ones. It's a comic book movie, yes, but it's very, very grounded."

In even more related news, The Hollywood Reporter spoke with Amy Adams as part of their ongoing Hollywood Masters series, where she shared one of her favorite moments on the Batman v Superman: Dawn of Justice set. While she wouldn't share too many details, she did admit that the scene involved both Batman and Superman, and there were "funny moments involving bat-suits." Take a look at what she had to say.

"I can't give too much away, but I'm coming into a scene and Batman and Superman are both in the scene, so I can say that. And it was just fun. Because they had been working together for a couple weeks and just running it, seeing this dynamic. I'll talk about this when we're promoting the movie and we can tell more. But there were definitely funny moments involving bat-suits and such."

Her comments are interesting since Warner Bros.' has an infamous "no-joke" rule in their superhero movies, but perhaps she was referring to moments between takes with her co-stars Ben Affleck and Henry Cavill. The actress also admitted that she hasn't seen a cut of the movie yet, except for the trailers that everyone else has seen.
