It was recently announced that Henry Cavill, who played Superman in several DC movies, would not be returning to the franchise, despite the fact that he announced he would be returning just weeks earlier.

The Dune actor shared more about the comparisons between the work he’s doing for the planet and the themes that will appear in the new Aquaman movie.

‘the beautiful thing [about Aquaman and the Lost Kingdom] My partner and I wrote the first treatment, and it was a 55-page treatment, and a lot of it has to do with my conversation with the UN about what’s happening with the melting ice caps.’

He continued: ‘There is no galaxy far away coming to destroy us or aliens from somewhere else. This is us ruining our planet. We have to come together and save our home.

‘I will always be Aquaman. There’s no one to go in there and take shit. There may be some other characters, too. I can also play other things. I can be fun, wild and charming.
