Gary Oldman considers this role without makeup his best, and the audience agrees with him

He managed to replicate a historical figure without the help of makeup artists.

You surely know as a master of transformation, capable of playing anyone from Dracula to Winston Churchill. But which role does the actor himself consider the pinnacle of his career? And no, it's not the iconic antagonist from “Léon” Norman Stansfield, nor Commissioner Gordon from “The Dark Knight.” Oldman, it turns out, is most proud of Lee Harvey Oswald.

Yes, the very Oswald from Oliver Stone's film JFK (1991). At first glance, the role may not seem the most striking—no crazy hairstyles or gallons of makeup. But that's where the secret lies.

Creative Freedom and "Frightening Accuracy"

Oldman admitted that working on the role of Oswald was an "exceptional experience" for him. The character was sketched rather sparingly in the script, and Stone gave the actor carte blanche:
He gave me some money and a few plane tickets and said, 'You know, just go and find out who this guy was. So I was both an actor and an investigator.'
The opportunity to "create" the character himself, to breathe life into him, made this role special for the actor. He literally immersed himself in the image, studied Oswald's biography, his manners, and tried to understand his motives.

Film critic Christian Gainey adds that the actor managed to portray the character in an unusual light. According to him, Oswald, played by Gary, is "actually just a patsy."
An intelligence agent whom the U.S. government accuses of killing Kennedy. At first, the idea seems absurd because we are used to thinking that this person killed the president, but it quickly becomes plausible when you watch Oldman's performance.

What is the film about?

"JFK" is not a traditional biopic but rather a political thriller investigating the circumstances surrounding the assassination of the 35th President of the United States. At the center of the plot is New Orleans District Attorney Jim Garrison (Kevin Costner), who, doubting the official lone assassin version involving Lee Harvey Oswald, begins his own investigation.

The film is a mosaic of memories, documentary footage, and event reconstructions, offering viewers an alternative version of what happened. The director doesn't provide clear-cut answers but rather raises questions, prompting viewers to think about how well we know history and who benefits from concealing the truth.
