It's always fascinating to see on-screen relatives who bear an uncanny resemblance to each other. Just look at Maia Mitchell and Bailee Madison from The Fosters or Poppi Monroe and Annie McElwain, who passed as twins in Disney Channel's Double Teamed. Any casting director will tell you that it's hard enough to find actors with strong enough chemistry to be believable as relatives. So if they also happen to look alike, it's safe to say that they hit the jackpot.
It's exactly why, in roughly 99 percent of the shows and films you've seen, the relatives usually look nothing alike. Actors can do a great job of portraying their familial bond, but sometimes it's kind of hard to ignore the fact that they don't look related at all. Still, we can at least appreciate the fact that casting directors usually try their best. And besides, we can understand why they'd value great acting skills and on-screen chemistry over physical appearance. See which fictional siblings don't look alike at all..
If you've seen the film, then you already know that Tina Fey and Amy Poehler had the best chemistry. Their connection felt so genuine that it often distracted us from the fact that they don't look like each other. While Tina has an oval-shaped face, dark brown eyes and dark hair, Amy has a much rounder face with bright blue eyes and blonde hair. As Richard Roeper from the Chicago Sun-Times perfectly put it: "though they look nothing like sisters, they’re believable as sisters." So yeah, we can forgive the fact that they have no resemblance.
It's really hard to believe that these two could be brothers, let alone twins. In the film, they play the Benedict twins, who are the result of an experiment where scientists combined the DNA of six fathers. Rather than creating the "perfect child," they created twins and they separated them. The two grow up to become total opposites in terms of their looks and personality. So perhaps the casting team thought they could get away with casting the two because their characters were technically created in a genetics lab. Still, we're just not convinced. Genetics lab or not, it feels a stretch to believe that the two share the same DNA, but I guess that's kind of the point.

Had we seen Jessica Alba and Chris Evans in a Fantastic Four promo, having no knowledge of who the characters were or what the film was about, we honestly would've assumed that they were a couple. They don't look related at all and they both look attractive enough to be the stars of a sappy rom-com. So of course, even as we watched the movie (and the sequel), there were times when we completely forgot that they were siblings. They did a decent enough job of displaying the whole sister-brother bond. But still, they looked way too different.
Fox Searchlight Pictures
While Toni played Sheryl Collette, a stressed-out mom of two, Steve Carell played her gay brother, Frank, a brilliant scholar who suffers from severe depression. The only thing that they seem to have in common is their skin tone because their facial features are very different. Toni has a slimmer, more narrow face than Steve does. Plus, Steve is green-eyed and dark-haired while Toni is a blue-eyed blonde. Maybe they could pass for half-siblings, but even that feels like a stretch.
Throughout most of the film, seeing Catherine and Julia together felt more like watching a nervous geek cater to her stunning boss, rather than her big sis. There were definitely moments to remind us that they were actually related, and we appreciate that they both have darker hair. But still, the fact that they worked together and didn't look alike threw us off a bit. They could totally pass for cousins, but biological sisters? ...Nope.
Laura's European features, blue eyes, and blonde hair was a stark contrast to Mark Ruffalo's darker eyes, hair, and skin. The only way they could've been siblings is if one of them was adopted. But despite their different looks, their characters, Sammy and Terry, shared the kind of adult brother-sister bond that feels all too familiar. They showed that while sibling relationships can be weird, awkward, and messy, it doesn't take away from the fact that they care for and love each other.
Of all the people to get cast as Matthew Broderick's sister, we never thought it would be Dirty Dancing star Jennifer Grey. At the time, Jennifer had naturally curly, dirty blonde hair and a heart-shaped face while Matthew had straight, dark brown hair and a more oval-shaped face. They clearly looked nothing alike. But on the bright side, they played out their sibling rivalry perfectly, with Ferris being the spoiled and entitled (but lovable) brat and Jeanie being the overlooked, angsty big sister.
Buena Vista Pictures
We can't be the only ones who struggled to see these two as biological sisters in the teen classic. Julia Stiles is of English, Irish, and Italian descent while Larisa Oleynik is of Ukranian descent. So it's understandable why they don't share a resemblance at all. Their opposite personalities also seemed to highlight just how different they were. But since they did such an awesome job of portraying their sibling tension on-screen, we can forgive the fact that they didn't look related.
We watched them bicker with one another for years on the show and we enjoyed every minute of it. But despite their on-screen brotherly connection, it was always tough to believe that they shared the same genetics because they have no similar features whatsoever. This was made even more obvious by the fact that their personalities are so different. Alan is practically a doormat who never succeeds with women and is a shameless freeloader. Charlie, on the other hand, was a confident and charming womanizer whose diet was at least 90 percent alcohol. The fact that they were still so believable as brothers is truly impressive.
We can at least give credit for the fact that Merle and Daryl were both white, blue-eyed, and in awesome shape. But as far as their physical attributes go, these were the only things they appeared to have in common. This, however, didn't stop the actors from portraying their brotherly bond in a way that felt almost effortless. Their relationship was far from perfect, but any viewer could tell that they sincerely loved one another. It's why when Daryl saw that his big brother had turned into a walker, our hearts broke.
Based on looks alone, there's just no way that Claire and Mitch could pass for siblings on Modern Family. Mitch is a blue-eyed redhead with super pale skin and Claire is a brown-eyed blonde. So from the beginning, it was difficult to pair them as people who actually shared the same genetics. Their heart-to-hearts and side conversations did serve as handy reminders that they're supposed to close siblings. But even after ten seasons, it still doesn't feel too believable.
If you've seen Rashida Jones on Black-ish, you probably remember that her character, Santamonica, has absolutely nothing in common with her sister. She's an aspiring housewife who seems allergic to working hard while Bow is a successful doctor and mother. But it's not just their personalities that are drastically different - the same goes for their looks. If Santamonica and Bow dressed alike and they rocked the same hairstyles, they still wouldn't pass for sisters. But we'll let it pass because they have great chemistry.
We simply adore Andre and Rhonda's playful rivalry, so it's a shame that they haven't had much screen time together on the show. But when they did share scenes, it was so obvious that they don't look related. Raven has very light skin, large eyes, and a pear-shaped face while Anthony has smaller, squinty eyes, darker skin, and a round face. We're guessing that the casting director chose to overlook the obvious differences because the chemistry was so great. And honestly, we can't blame them.
Yes, they're both stunning, but there isn't an ounce of resemblance between Sam and Dean. Still, the way that their relationship evolved throughout the show more than made up for it. Though they worked great as a team, their decisions and sacrifices often had a negative impact on their relationship. It was like watching a roller coaster ride. But their continuous effort to work through this and figure out how to actually be family made their brotherhood feel all the more genuine.
Klaus and Elijah's relationship was beyond complicated. Especially since it often depended on Klaus's moods or his sudden impulse to dagger his siblings. We know that they were technically half-brothers, so it's understandable that they don't look too alike. But even so, it's clear that they don't share any features at all. The constant back and forth between these two being enemies and being BFFs changed fast enough to cause whiplash, but their brotherly bond (while dysfunctional) was still felt very real.
They might have exchanged countless insults and punched each other in the face a few times, but there's no denying that the Salvatore brothers had a unique and powerful bond. Seeing their relationship grow from a bitter rivalry to a close friendship honestly warmed our hearts. And if we're being honest, this made it so much easier to ignore the fact that they look nothing alike. Stefan was slightly taller with short brown hair and green eyes, while Damon had black hair with blue eyes and more angular facial features. Even despite this, the actors were very convincing as brothers on screen.
