According to screenshots published by Entertainment Weekly, Beckinsale publicly responded to Ruffalo's post and called him out for not reaching out to her after her firing.
"It must be nice to not be fired by your agent for liking a post about a ceasefire and not being for killing children," she wrote.
"I guess having a p***s in Hollywood really helps because you weren't fired by the same agent we shared. She sent me a gift a week earlier, so we had no issues. But I liked a post about a ceasefire and was fired the same day as Susan Sarandon, two days after the strike ended, after nine months during which none of us could work," she stated.
She also referenced the 2023 Hollywood actors' strike, while Sarandon had previously spoken about being marginalized in the industry due to her views.
The actress emphasized that at the time she was fired, she was going through a difficult period in her private life. She had just learned that her mother Judy Loe, who suffers from brain cancer, had very little time left, while her stepfather Roy Battersby had suffered a severe stroke and was diagnosed with two types of cancer. During that time, Beckinsale was caring for both.
"I was preparing to go to England to get him so I could take full care of him, and then I was fired in two sentences. This happened after 12 years of friendship with my and your agent, who knew what I was going through," she wrote.
Although she did not name the agent, she pointed out that she had tried to contact Ruffalo several months ago, but he did not respond. She later added that she associates such behavior with male privilege, which, she says, is also present among people considered to be good.
"Obviously, I didn't get a response. I truly support Mark Ruffalo and everything he does, but no, I won't get a response here or ever," she stated, adding: "I sent him a message several months ago and he ignored it. There's no reason for him to respond now."
