• Stunt doubles fill in for actors whenever action sequences get a little too intense.

• Here are some of Hollywood’s biggest A-list actors and their trusty doubles.

If there’s a fire, explosion, or particularly cool action sequence in the next film you see, chances are a stunt double was on hand to take the heat. These skilled performers not only have to conquer on-screen physical challenges but they’re required to look the part as well — down to the exact same hair, costume, and makeup as their counterpart.

We found the stunt doubles of some of Hollywood’s biggest stars and the side-by-side pictures are pretty uncanny. Seriously, blink and you’ll swear they’re the same person.

Chris Hemsworth and Bobby Hanton

It takes pure dedication and willpower to be Chris Hemsworth’s stunt double. Bobby Hanton, who subbed in for Hemsworth during "Thor,""Captain America," and "The Dark Knight," told Buzzfeed that he had to eat 35 meals a day in order for his body to look "anywhere near" the action star’s physique.

"I also have to train twice a day," he said. "Chris is naturally a monster and all he has to do is look at weights and he grows."

Chandler Riggs and Emily Brobst

Who says your stunt double has to be the same gender? Chandler Riggs, who plays Carl on "The Walking Dead," turns to Emily Brobst when action scenes get a little too intense. She’s actually 15 years his senior, but if you glance really, really quickly the pair look pretty identical.

Liam Neeson and Mark Vanselow

Mark Vanselow has a particular set of skills — one of which includes playing stunt double to Liam Neeson in "Taken." However, according to Vanselow, Neeson actually does a lot of the hardcore action work himself.

"He does the majority of the fighting, he really does," he told the Daily Star. "He’s tough. We usually end up beating each other up during rehearsals. What you see on screen is mostly him."

Johnny Depp and Tony Angelotti

Blink and you might just mistake Tony Angelotti for his counterpart Johnny Depp. The stunt double has filled in as Jack Sparrow for three of the "Pirates of the Caribbean" movies and definitely has that whole rough around the edges look down pat.

Sarah Michelle Gellar and Sophia Crawford

Who better to fill in for Buffy the Vampire Slayer then an actual trained martial artist? Sophia Crawford took on the teen hero’s stunts from 1998-2000, which included that epic first fight between Buffy and Faith.

Daniel Craig and Ben Cooke

If you’re the stunt double for 007, hands down you’ve won it all. Ben Cooke took on Daniel Craig’s stunts in three Bond movies and he told UrbanDaddy that his job involved plenty of "fire and a lot of explosions."

"All of the [Bond] movies are different on what they require," he said. "A lot of car crashes and wire work and bomb control. That sort of stuff." You know, just a typical day at the office.

Jennifer Garner and Shauna Duggins

Not only did Shauna Duggins fill in for Jennifer Garner on the set of "Alias," but she was the first female stunt performer to be nominated for an Outstanding Stunt Coordination Emmy. Also, she's close friends with Garner and went onto double for the actress in "13 Going On 30,""Elektra," and "Daredevil."

Chris Pratt and Tony McFarr

Nope, you're not seeing double. That's Chris Pratt with his stuntman Tony McFarr on the set of  "Guardians of the Galaxy Vol. 2." The actor posted a sweet snap of his double on Instagram after shooting finished, writing:  "Here's me and my stunt-man Tony McFarr. Been working with Tony since "Jurassic World." Love you buddy! Happy wrap!"
