The most successful DCEU release in North America - as box-office champ and cultural phenomenon - remains last year's "Wonder Woman" ($412.6 million).
This also follows the Birds of Prey movie news, which will see Margot Robbie's Harley Quinn paired with a female director, Cathy Yan, and an ensemble of female characters.
Cavill has appeared as Kal-El in three DCEU films: Man of Steel, which was released in 2013 and kickstarted the cinematic universe, the widely-panned Batman v. Superman (2016) and the under-performing Justice League, which was released previous year.
The report adds that, as a Man of Steel sequel is years away from production, the studio would prefer to reboot, thus closing the door on Cavill's return.
It's unlikely that this is all a ruse to drum up interest for a new Superman movie or appearance, and is instead a failed contract negotiation finally going public. The latter two struggled at the box office and were panned by critics. While Man of Steel was well received, Dawn of Justice and Justice League were... not.
It doesn't look good for the future of the Justice League..
The eight-episode Netflix adaptation of the bestselling medieval fantasy book series by Polish author Andrzej Sapkowski centers on the protagonist Geralt of Rivia, a monster hunter known as a "Witcher" who travels the countryside slaying terrifying beasts.
If Harington were to land that role, he would be following in the footsteps of former Game of Thrones star Jason Momoa (Khal Drogo) in making the leap from television to a huge big budget studio film. This report from Deadline may be controversial news, but a few years down the road, Michael B. Jordan may prove himself to be the greatest Superman to ever grace the screen.
