It was supposed to be a big kick-start for the DC Extended Universe, after a limping beginning.

But despite Wonder Woman’s success, Justice League has flopped and embarrassingly so.

Having failed to make over $100 million in its opening weekend (less than Thor Ragnarok, Wonder Woman and Batman v Superman), the DC superhero team up is going to make a whopping loss.

According to Forces this could between $50-100 million for Warner Bros, having calculated a final budget and marketing cost of $600 million. Here’s the break down.

Following reshoots Justice League’s production budget hit $300 million, with $150 million spent on marketing taking it to $450 million.

Add home entertainment ($60 million), salaries ($50 million) and additional costs and you end up at that incredible $600 million.

So far the film has made just $278 million worldwide and Forbes has calculated a final loss of around $50-100 million assuming the film does as well as Batman v Superman: Dawn of Justice.

Yesterday Aquaman star Jason Momoa hit back after bad reviews and poor box office for Justice League.

Momoa told Entertainment Weekly: “I try to stay the f**k away from what people say.

“Some of my friends said, ‘Justice League isn’t doing well’ and it kind of bummed me out. 

“But I didn’t want to look it up. I don’t want to look up the bad and the negativity. I don’t think that’s useful; it doesn’t help.”
