The Next Generation: Millie Bobby Brown and Milly Alcock

The conversation around Portman’s look-alikes has shifted in recent years with the rise of two young actresses who bear a striking resemblance to a younger version of Portman, particularly from her *The Professional* and *Star Wars* days. These comparisons highlight a shared youthful charm and distinct facial structure.

Millie Bobby Brown: The Stranger Things Resemblance

The internet went into a frenzy when fans of *Stranger Things* breakout star Millie Bobby Brown noticed her uncanny similarity to a young Natalie Portman.

The resemblance is most pronounced when comparing Brown in her early roles, like the character Eleven, to Portman in her 1990s films.

The shared features include a similar brow shape, a youthful, slightly rounder face shape, and the intense gaze that both actresses possess, lending them a maturity beyond their years.

While some argue Brown's face shape is different from Portman's adult look, the youthful charm and overall aesthetic make the comparison a popular and often-cited one.

Milly Alcock: The New DC Hero Doppelgänger

Milly Alcock, who rose to prominence as the young Princess Rhaenyra Targaryen in HBO's *House of the Dragon*, is the newest name to join the list of Portman look-alikes.

The Australian actress has been praised for her intense on-screen presence, which some viewers have compared to the dramatic intensity of Portman's early performances.

The comparison has gained new traction following Alcock’s recent major casting as Supergirl in James Gunn’s new DC Universe, a high-profile role that mirrors the franchise-leading parts Portman took on with *Star Wars* and the MCU.

The similarity is often noted in their eyes and the structure of the upper face, which gives them a similar look of focused determination.

The Lesser-Known Resemblances: From Jessica Biel to Rachel Weisz

Beyond the primary three, several other actresses have been cited over the years for possessing a similar aesthetic or for being frequently mistaken for Portman or Knightley, further solidifying the "Portman-type" as a specific, recognizable look in Hollywood.

Jessica Biel: The Subtle Resemblance

Actress Jessica Biel is another celebrity whose features occasionally draw comparisons to Portman.

While Biel has a more athletic build and a distinct jawline, the resemblance is often noted in specific photos where their hair and makeup are similar, particularly around the eyes and forehead.

This subtle similarity is a fun piece of celebrity trivia that often surfaces in online doppelgänger discussions.

Rachel Weisz and Kate Winslet: The Mistaken Identity Club

Interestingly, Keira Knightley has publicly admitted to being mistaken not only for Natalie Portman but also for fellow acclaimed British actresses Rachel Weisz and Kate Winslet.

This suggests a broader category of brunette, highly talented, and aesthetically similar actresses whose classic European features often lead to confusion, placing Portman's look at the center of this celebrity Venn diagram.

Other actresses occasionally mentioned in the broader conversation due to a similar delicate bone structure or eye shape include Mila Kunis (who has worked with Portman in *Black Swan*) and, in some very specific angles, even the adult film star Sasha Grey, though these are less mainstream comparisons.

The enduring mystery of the celebrity doppelgänger continues to fascinate. Whether it’s the historical casting decision of Keira Knightley as a decoy, the youthful mirror image of Millie Bobby Brown, or the rising star power of Milly Alcock, Natalie Portman’s distinct beauty has created a unique legacy of celebrity look-alikes across generations and major film franchises.
