The actresses Jessica Chastain and Bryce Dallas Howard are often confused with one another because of their similar appearances. Fans are under the impression that others may have been split apart at birth since they share such a striking similarity. If you've ever had the feeling you're experiencing, your eyes may be playing tricks on you due to these Hollywood Celebrity couples.

1. Sarah Hyland and Mila Kunis

The actresses from "Modern Family" and "Ted" have both said that they are often confused with one another. After first contacting one another in December 2010 at a party hosted by Nylon, the two concluded that they would pose as one another in public. Hyland told InStyle that the woman approached her and said that she, too, is often addressed as "me." "She said that to keep her youthful spirit alive, she pretended to be me on occasion," When I asked her whether I could impersonate her the next time someone asked me if I was here, she stated it was OK with her.

2. Isla Fisher and Amy Adams

Even though they have different eye colors, the actresses from "Arrival" and "Bachelorette" are often mistaken. In her cover story for Allure, published in January 2009.

3. Liam Neeson and Ralph Fiennes

Neeson has said that people often get the actors from "Harry Potter" and "Taken" confused with one another. "He is one of my very finest and closest friends. Neeson said this when he appeared on The Jonathan Ross Show in 2014. "I keep getting people and everything putting me up with Ralph because we have very similar features," Neeson added.

4. Keira Knightley and Natalie Portman

In the Phantom Menace," Keira Knightley played the role originally intended for Natalie Portman. No matter how you match them, Keira Knightley and Natalie Portman have an uncanny resemblance. This holds regardless of whether their hair is short or long, wavy or straight.

5. Katy Perry and Zooey Deschanel

The actress from "New Girl" was initially annoyed when fans mixed up her character with another one. When asked about it by MTV in 2009, Deschanel said, "It's a little bit bothersome, to be quite candid." The only thing that links us together is the fact that we have a superficial resemblance.

Since then, it seems like the actress has become more accepting of the parallels. In a conversation with David Letterman in November 2012, she said, "I was relieved because everyone kept saying 'this girl looks so much like you.'" "And then I met her, and all I could think was, 'Thank God she has some good looks!'" My biggest concern was that she might turn out to be an ugly person.

6. Will Ferrell and Chad Smith

Since both the comedian and the drummer for Red Hot Chili Peppers are aware of how similar they seem, they decided to settle their rivalry by competing in a drum-off on "The Tonight Show Starring Jimmy Fallon" in 2014. Even their clothing was an exact match.

7. Bryce Dallas Howard and Jessica Chastain

Chastain remembered how, subsequently, she was mistaken for the "Jurassic World" actor and how she sometimes chooses to roll with the punches when this happens. However, both are excellent sports about it and have made an effort to clarify everything that's been going on.

Howard created a little dubsmash video in which she explains the characters to the audience. It piqued Chastain's interest, and he posted it on Instagram. In May of 2015, Chastain posted a humorous photograph on Twitter in which she poked fun at the fact that most people had trouble telling them apart.

8. Javier Bardem and Jeffrey Dean Morgan

Jeffrey Dean Morgan (left), who plays Rick Grimes on "The Walking Dead," and Javier Bardem had extremely similar appearances in their younger years. When Jeffrey Dean Morgan first walked through the doors of Seattle Grace Hospital on the ABC medical drama "Grey's Anatomy," we had to look twice to ensure he wasn't the Oscar-winning actor.

9. Penelope Cruz and Salma Hayek

In reality, the two are pretty close friends with each other and often pose for selfies together. Huevos, the Spanish word for eggs, is a nickname the two of them have for one another.

10. Jeremy Renner and Nathan Fillion

When we are flipping through the channels and coming across ABC's "Castle," we always believe that we will see a celebrity from "The Avengers." Fillion came to Twitter in 2014 to talk about the numerous celebrities his followers have said he resembles. How did he grade Renner? "Brothers," Fillion noted that he had also discussed their similarities with Jason Bateman, who looks quite similar to Fillion.

11. Millie Bobby Brown and Natalie Portman

This list features Natalie Portman not once but twice! In January 2018, viewers of "Stranger Things" began comparing Millie Bobby Brown, who plays Eleven in the show, to a younger version of Natalie Portman on Twitter.

12. Millie Bobby Brown and Halsey

Given their physical similarities, the singer Halsey shared with Jimmy Fallon her opinion that Millie Bobby Brown would be an excellent choice to represent her in a film adaptation of their life story. Halsey said that Millie would be an excellent choice. However, I do not believe that I am well-known enough to be considered for the role of Millie. It's almost eerie how similar our appearances are to one another. It's as if someone said, "Oh no, we simply look like sisters."

13. Jesse Eisenberg and Michael Cera

We aren't the only ones who get Michael Cera (on the right), and Jesse Eisenberg (on the left) confused. According to actor Michael Cera of "Arrested Development," people often get these performers confused with one another. In an interview with the New York Post in 2014, Michael Cera said, "I once ran into Jesse on the street, and he informed me that he gets it once a day." "Many individuals believe that he is Michael Cera."

14. Jennifer Connelly and Demi Moore

In the 1990s, Jennifer Connelly (shown on the left) and Demi Moore concurrently appeared in several critically acclaimed films. We might not be able to tell the difference between these two if it weren't for Connelly's fuller brows.
