There’s a scene late in “The Apprentice,” the new film directed by Ali Abbasi about the relationship between Donald J. Trump and attorney Roy Cohn, that’s akin to Dr. Frankenstein realizing in horror just what he has made.

An ailing Cohn (Jeremy Strong) is being uncomfortably feted at the Florida estate Mar-a-Lago for his birthday. His longtime protege, Donald Trump (Sebastian Stan), seems to have ascended to the height of his powers (how things would develop three decades later is not yet known). Empowered by his own hubris, Trump builds and borrows and bangs with impunity, and a freewheeling sense of gleeful combativeness.

After an aggressive and somewhat insulting birthday toast, Trump wheels out an American flag birthday cake festooned with sparklers, an ode to Cohn’s oft-repeated professions of love for America. Cohn, for the first time in the film, looks shaken. It’s the icing on top of what he already suspects: that he has created a monster — a monster to whom America is a joke, a punchline, something to be devoured, like a can of Diet Coke, a blond model or a bottle of cheap speed, all things that Donald consumes ravenously over the course of the film.

Abbasi’s “The Apprentice,” written by political reporter Gabriel Sherman, is a portrait of the former president as a young man. Stan delivers the performance of his career, embodying Trump from the early 1970s to the 1990s. The plot concerns Trump’s learning at the feet of Cohn, the powerful attorney and political fixer.

Abbasi opens the film with punk rock flair, with young Donald, his blond, Redford-inspired coif whipping in the wind, hitting the streets of Manhattan, making his way inside the dark, luxe interior of the private Le Club. There, Cohn will send over one of his men to invite Donald to dinner with his coterie of gangster clients. Donald is a striver, looking to please his cruel father Fred (Martin Donovan), and he hopes that with Roy on his side, they’ll best a housing discrimination lawsuit brought against them by the Department of Justice.

It’s through this lawsuit that Cohn imparts the three rules that Trump has since lived by. One: Attack, attack, attack. Two: Admit nothing, deny everything. Three: Always claim victory, never admit defeat. As Roy lays out these lessons, and as Trump parrots them as his own years later during the writing of his book, “The Art of the Deal,” it’s almost sickening to reflect on how we’ve seen these precepts play out in the governing of the United States of America.

This is the method by which Abbasi and Sherman go about making their argument about Trump. They lay it all out for the audience to see, but don’t spell out the message that we’re to take away from it all.

Both the film’s style and the performances evolve to capture the eras we traverse. Stan and Strong’s astonishing performances also deepen and develop over the course of the film. Initially, Stan imparts only a small flavor of the familiar Trump flair; as his Trump ages, his delivery becomes more pronounced, his accent and cadence informed by both his father Fred and his mentor Roy. Strong is transformed as Cohn, slack-jawed and dead-eyed but constantly in motion, propelling his lithe, tanned body forward with a driven intensity in business and in pleasure.

Some may want “The Apprentice” to go further. It does humanize Trump. But it also presents a plainly obvious depiction of how a man can be a monster with the right personality, background and guidance. What more could it possibly say?
