Charlie Sheen has been known for his druggy behavior for a while now, but one of his best moments looking this way was back in the part he played in Ferris Bueller’s day off when he looked REALLY strung out. That look was something he came by naturally at least at that time since he stayed up for around 48 hours to get the right appearance of someone that was as messed up as they could be while still remaining functional. If you’ve ever pulled an all-nighter or two in college or even just stayed awake for reasons of your own then you know how it feels the next day when the sun rises and your eyes haven’t closed for more than a few seconds at a time. The human body needs sleep or it begins to go into various modes that will allow it keep functioning so that it won’t just shut down due to exhaustion. The outward effects are quite noticeable since most people, without the use of caffeine or other stimulants, will look as though they’re ready to pass out at any given moment after not sleeping for so long.
Sleep deprivation is a very serious matter most times but when done now and again it can be something that’s more troublesome than life-threatening. After about 24 hours without sleep the body will become less coordinated, judgment and memory will be impaired, and it will seem as though the person is legally drunk as they stumble about. Sleep deprivation hits everyone differently however and such symptoms might take a while to truly manifest. After 36 hours however it’s said that the lack of sleep will start to have a negative impact on a person’s health, as a person’s blood pressure can increase, they might feel as though they’re dehydrated, and they could experience intense emotions that they simply don’t understand. By the second day, meaning when a person has been awake for 48 hours, the body will start taking over as a method of control to keep itself from any further deprivation. Microsleeps will occur that can last from one second to half a minute in duration. Once the individual wakes up they are typically disoriented and have trouble focusing for any period of time.
For this role Charlie Sheen was no doubt closely watched being as most directors don’t want to be responsible for their actors keeling over at any moment after subjecting themselves to such ill treatment. But if it was done with consent then there’s no one to blame really and for the most part it looks like Charlie was able to get the sequence done without too much trouble. It did make for a funny scene with Jennifer Grey since she was the one character besides Rooney that was so aggravated by Ferris’ antics throughout the movie and to see her giggling and falling over herself at the end of the scene as Sheen watched on sleepily was highly amusing.
You can bet he got some solid sleep after this scene was shot, as most people would probably pass out on the couch.
