Jason Momoa packed on the PDA with his stunning girlfriend Adria Arjona at the star-studded Supergirl premiere in London on Thursday night While leading lady Milly Alcock – who stars as main lead Kara Zor-El / Supergirl – stunned in white gownThe drama began when Lois and Clark star Dean Cain faced backlash from Superman fans after seemingly mocking Milly’s appearance on social media.The conservative actor, 59, came under fire after responding to a meme that likened her to the primitive, ape-like human Cha-ka from the 1974 series Land of the Lost.A troll responded to Cain on X with an unflattering photo of Cha-ka and asked, ‘And why does she look like this guy?’Cain then responded, ‘Dang it… I laughed,’ followed by a smiling emoji.The actor’s reaction to the cruel comparison quickly spread on social media, leaving a number of superhero fans outraged. ‘What a fantastic way to kill your legacy. And what a glorious way to lose the respect of millions of kids that looked up to you three decades ago. What a disgrace,’ wrote one person.Another commented: ‘Your Superman performance is never going to be looked back upon fondly, your bitter jealousy has tainted any legacy you had left.’Cain eventually clarified that he ‘never said she was ugly’, but seemed overall unconcerned by the backlash.

The Sydney-born actress told Variety Magazine that she was ignoring the criticism. ‘[The criticism] is from a lot of people whose profiles have no photo, who are burner accounts, or someone’s name and then ‘Dad of four, Christian,’ which is hilarious to me,’ she said.’I mean, whose opinion do you really care about? If you’re p***ing the right kind of people off, you’re doing okay!’It comes after Milly said she’s bracing for backlash ahead of the release of Supergirl because she’s used to women being harshly scrutinized by fans of popular franchises.Reflecting on her time starring in the Game of Thrones spin-off House of the Dragon, Milly told Vanity Fair, ‘It definitely made me aware that simply existing as a woman in that space is something that people comment on.’She added: ‘We have become very comfortable having this weird ownership of women’s bodies. I can’t really stop them. I can only be myself.’Supergirl is the second film to be released in the newly rebooted DC Universe.It follows last year’s Superman, which grossed $618million worldwide and won praise from critics.The blockbuster, which was written and directed by James Gunn, sparked intense debate upon its release, with many fans and critics believing that the plot drew parallels to the Israel-Palestine conflict.
