What can you say about Christopher Nolan's masterpiece that hasn't already been said? The film is magnificent in every respect. Written and directed by Mr. Nolan, it's his finest film to date and that says a lot. Even if you are not a history buff, the film has enough drama and energy to appeal to anyone.
And what star power. Casting is impeccable. Cillian Murphy gives a tour-de-force performance in the title role. Robert Downey Jr. is remarkable as Lewis Strauss. Emily Blunt, Florence Pugh, Matt Damon, Josh Harnett, Kenneth Branagh Jason Clarke, Benny Safdie, Tom Conti, Casey Affleck, and so many others are all just amazing.
The script is brilliant. So much history and science to absorb yet easy to digest within Mr. Nolan's screenplay. Some scenes are not historically accurate but still make for good drama. In his typical fashion, Mr. Nolan does like to play with chronology but switches from color to black & white to help frame the different time periods.
The visual details are incredible. Nothing is out of place throughout the various time periods. A standout is also the sound production. I almost never pay too much attention to the sound of a film, but here, the sound is so important and precise, it's like its own character.
Long after the phenomenon of "Barbiheimer"(both highly anticipated films coming out the same day) fades, people will remember "Barbie" for its huge box office and personal triumph for Greta Gerwig, but "Oppenheimer" will be remembered as one of the greatest cinematic achievements of all time.
