Dozens of real critical figures are accounted for inOppenheimer, some for a scene, others as main characters.

Despite playing a supporting role, Damon is one of the biggest stars in the massive cast ofOppenheimer.

Perhaps it takes one to know one.

I have ever worked for.

He is most demanding.

He is most critical.

He is always a driver, never a praiser.

He is abrasive and sarcastic.

He disregards all normal organizational channels.

Oppenheimer is a film by Christopher Nolan, which follows the theoretical physicist J. Robert Oppenheimer, the man behind the atomic bomb. Cillian Murphy will play the titular role, with the story based on the book American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer by Kai Bird and Martin J. Sherwin.

He is extremely intelligent.

He has the guts to make timely, difficult decisions.

He is the most egotistical man I know.

He knows he is right and so sticks by his decision.

Each couldn’t have done it without the other.

There was a lot of genuine affection there."

Both Cillian Murphy and Robert Downey Jr. won Oscars for their performances, while Emily Blunt was nominated.

It’s brazen and bizarrely funny in the midst of so much darkness.

But the comic relief here is more than that.

Damon’s general is also one of the chief symbols of the danger of nationalism inOppenheimer.

His resolute attitude and bravado become as much a red flag as an amusement.
