Onscreen Relatives Who Look the Least Alike

Movies and TV shows would be nothing without the actors who inhabit our favorite characters - but sometimes Hollywood tries to trick us, casting related people who don't look alike at all. Movies sisters and movie brothers often have next to zero familial resemblance, making the film slightly less believable.

Finding the right person for the right role is never an immediate decision; it’s a process that takes a great deal of time, and is undertaking by highly trained casting directors who have spent a career developing an eye for this sort of thing. Casting director generally try their best but sometimes their best efforts fall short, and we are left with characters that simply don’t look like they are related at all.

Tina Fey and Amy Poehler’s movie Sisters, while hilarious, continues the practice of hiring actors who don’t look alike to portray siblings.

Far from it. Vote up the movies siblings below that you think are the most jarring and distracting from their films on the whole.
