Along with many other mental illnesses, OCD isn't often showcased in popular films and TV series.
Though it affects one in 40 adults and one in 100 children in the U.S., it's rarely ever talked about in the media.
That being said, there have been a handful of movies that have dared to depict the disorder as accurately as possible.
Scroll down and see which flicks got it right with their portrayals of OCD.
