LOS ANGELES, CALIFORNIA: Robert Downey Jr's newest movie 'Oppenheimer' has him giddy. He even said something at the London premiere that would enrage 'Iron Man' fans. In a video that Deadline tweeted, he said, "Just going to flat out say it: This is the best film I've ever been in, I cannot wait for you all to experience it."

Robert's character in the Christopher Nolan movie is of Lewis Strauss. Talking about the film he said, "No matter what your expectations are about the film that tells the story of the development of the atomic bomb during World War II, it transcends that." He added, "This is what a summer blockbuster, when I was growing up, used to be." ''It just kind of, like, changed your life. But again, you know, it's why Chris Nolan is who he is," Robert continued.

And reviewers concur, with The Telegraph's Robbie Collin gushing on Twitter, "Am torn between being all coy and mysterious about 'Oppenheimer' and just coming out and saying it's a total knockout that split my brain open like a twitchy plutonium nucleus and left me sobbing through the end credits like I can't even remember what else."

'OPPENHEIMER is...incredible'

Bilge Ebiri, a critic for Vulture, said "'OPPENHEIMER' is...incredible.The word that keeps coming to mind is fearsome." Critic added, "A relentlessly paced, insanely detailed, intricate historical drama that builds and builds and builds until Nolan brings the hammer down in the most astonishing, shattering way."

The cast of the movie, which included Matt Damon, Emily Blunt, Cillian Murphy, Rami Malek, and Florence Pugh, left the red carpet at the film's London premiere as soon as word of the SAG-AFTRA strike spread. According to Nolan, the actors left the event early to "go and write their picket signs" in advance of the "strike by the actors' union," as reported by DailyMail.

The use of uncontrolled AI, the proliferation of streaming services, and how little performers get paid for such shows and movies are some of the factors that led to the strike. In a red-carpet interview with Variety the evening of the London premiere, Damon stated that the actors will "walk obviously in solidarity" "once the strike is officially called."
