People with OCD are frequently represented in movies, TV series and motion pictures as having quirky small behaviors that have no bearing on their daily lives. How ridiculous it is for them to turn the lights on and off! Take note of the precise manner in which they pass through a door! The distinction is that such habits typically don't interfere with someone's life if they just make sure their garage door is closed or checks their locks. After making that brief check, they continue with their day. An OCD sufferer is plagued with worry and anxiety and spends the better part of an hour a day in their obsessions and compulsions. 

There are several causes for the widespread misperceptions about OCD. Social media, casual chat, and self-diagnosis by people who don't actually have the illness are all factors. However, they are not the only guilty ones. The aforementioned is exacerbated by movies and television productions, which reinforce stereotypes and present OCD as a witty, eccentric, and entertaining disorder. 

Here's is interesting example of movie OCD.

The Aviator, - direction by Martin Scorsese

Leonardo DiCaprio plays Howard Hughes in the movie, a pioneer in aviation and film producer who was seen as "eccentric" due to his frequent indulgence in compulsive behaviors. 
Throughout the movie, Hughes descends into the depths of his illness and partakes in the following:
1] Using such force and duration that his hands bleed from being scraped. 
2] refusing to touch anything (like spectacles) that other individuals have touched 
3] drinking milk only after carrying out a difficult and unique ritual 
4] requesting bottles that haven't been opened 
5] consuming the same food every night 
6] bringing his own soap to use for hand washing 
7] Cellophane-wrapping steering wheels 
8] carrying out intricate processes to finish simple jobs 

9] Cellophane-wrapping steering wheels 
10] carrying out intricate processes to finish simple jobs
11] being unable to leave his house due to his overwhelming fear of germs 
12] Getting worse until he withdraws completely 
The film was not particularly marketed as being about OCD, and it's reasonable to say that many viewers saw it without being able to pinpoint Hughes's precise condition (blaming it, once more, on Hughes's eccentric nature). 

However, the film does depict the heartache that comes with compulsions, as well as how time-consuming, unreasonable, and anxious they can be, and how, at the time, they seem to be the most essential thing in the world. The fact that the movie, in contrast to most movies, is about a real person and real-life events may be the reason the portrayal is so accurate. It doesn't hurt to have DiCaprio in the main part. Other films depict the irrationality and time-consuming nature of compulsions in a reasonable way. As Good as it Gets, starring Jack Nicholson as OCD-affected writer Melvin Udall, is one of these movies.
