10 Perfectly Cast Movie Siblings VS 10 That Definitely Involved The Milkman

When it comes to casting siblings, parents, or children, the directors can make a really good decision or a very bad one. Some actors look like they share the same DNA despite not being related whatsoever in real life. They only need to nail the chemistry between siblings and we can totally be convinced that they share the same bloodline.
On the other hand, we have actors who have next-to-no resemblance playing related family members. Their differences are so obvious they can be distracting as hell. Some of these duos even make us question whether the mom has an affair with the milkman or not.
So let’s take a look and see which case is a success and which is a failure. Here are 10 perfectly cast Hollywood siblings and family members versus 10 that definitely involved an affair.
