It's always fascinating when actors who are related in real life share the screen. But sometimes, those actors are also related in the exact same way as the characters they're playing are, and it's amazing.
This adds a layer of realism to the film or TV show. Actors who are related look like each other in a way Hollywood just can't fake. Plus, it can make the acting process more natural. After all, a brother and sister who are playing brother and sister are bound to give realistic performances. Sometimes actors who are related use this familial bond to create performances that have autobiographical elements to them.
It's relatively common for the young children of actors to play their parents' kids on screen. After all, these kids are often new to acting and are already comfortable with their parents. Many kids have gone from roles like these to becoming actors in their own right.
On this list, you'll also find siblings and spouses playing characters who are actually siblings and spouses. Here are 15 Movie Families You Didn't Know Were Actually Related.

Henry Fonda won his first Oscar for the film.
11 Elizabeth Taylor and Richard Burton - Who's Afraid of Virginia Woolf?

She explained, "People thought that making the film was the beginning of the end of my marriage, but I don't really think it was. Tom and I were close then... Stanley wanted to use our marriage as a supposed reality. That was Stanley: He used the movie as provocation, pretending it was our sex life...but obviously it wasn't us." They also played a couple, though not a married one, in two more films: Days of Thunder (1990) and Far and Away (1992).
