Dark Phoenix (2019)

Dark Phoenix (2019) marks the second failed attempt to bring the Dark Phoenix saga to screen, and it fell even harder than the first. With a $200 million production cost and a worldwide gross of only $252 million, the studio suffered an estimated $133 million loss—31% worse than Cats' $114 million deficit. This catastrophic underperformance makes Dark Phoenix the most expensive X-Men film ever at $200 million, yet it earned 33% less than the average superhero movie in 2019. The sequel's 22% box office drop from the prior X-Men film sealed the franchise's fate.
