15+ On-Screen Siblings That Look So Much Alike They Could Pass As Actual Relatives In Real Life
If there's an underrated behind-the-scenes person in the making of a movie or a TV show; it's the casting director. It's easy to applaud the directors, producers, and even the costume designers, but what most people overlook is the sheer talent of casting directors for finding just the perfect actor for a certain character—especially when they are choosing between actors that are just starting out.
Casting directors will take into consideration the acting styles, physique, originality, creativity, and listening skills of an aspiring actor to decide if they are fit for a role or not. Sometimes, there are even instances that they like an actor's personality so much, that they just make a whole new character for them; just like how Chris Colfer bagged the role of Kurt Hummel in Glee!
One satisfying aspect and a clear sign that the casting directors did their job right is seeing an on-screen family actually looking like a family. Take the actor of Adam Groff and his dad, the principal, in Netflix's Sex Education, for example—it's hard to believe that they aren't actually related in real life because, well look at their faces, especially the nose!
Now, have you noticed some on-screen siblings that look eerily similar to each other they could pass as actual siblings in real life? For instance, have you ever noticed how Georgie Henley and William Mosely as Lucy and Peter Pevensie look like an actual brother and sister duo?
