“Celebrity Lookalikes: 40+ Doppelgangers That Will Leave You Astonished”

Many people mix up "The Avengers" and "Westworld," and it's not just fans who get them confused. On the Late Late Show with James Corden, Salanda joked, "My mom still thinks that I’m in Westworld. Years ago, she thought that I was in Traffic. 'Mom, you did not give birth to Thandie Newton.'"

"I met Thandie at the Golden Globes a few years ago," the Avatar star shared. "I hugged her and sort of surprised her because I didn't explain why I was getting close. I asked, 'Do people ever mix us up?' And she responded, 'Who are you?'"

The actor from "The Walking Dead" is frequently confused with the Spanish actor who won an Oscar, Javier Bardem. He once used their striking similarity to play a trick on Bardem:

In an interview on The Talk, Morgan shared that at a red carpet event, he got frustrated with photographers who were calling him 'Javier.' So, he raised his middle finger at them. Surprisingly, people thought Javier Bardem was responsible for this rude behavior.

When the second season of the TV show "You" came out, fans on Twitter noticed that the main actress, Victoria Pedretti, looked a lot like Hilary Duff, who stars in "Younger."

A fan also pointed out that in the past,Hilary Duff and Penn Badgley, who plays the (crazy) boyfriend in "You," had a romantic storyline together on the show "Gossip Girl."

When Khachanov played against Rafael Nadal in the US Open, fans noticed that the Russian tennis player looked a lot like the Australian actor.

Khachanov also made a joke about how much they looked alike. He posted a picture from Hemsworth's Instagram and playfully said he would be glad to take Hemsworth's place at a movie premiere.

Even though they have different jobs -Ferrell is a famous actor and producer, while Smith is the drummer for the legendary band Red Hot Chili Peppers - they look so much alike that they could be brothers.

They both even went on The Tonight Show and had a funny competition playing the drums against each other. Surprisingly, Smith won the contest.
