20 Things You Somehow Missed In The Truman Show

20. Truman Takes Vitamin D Supplements (Because He Never Sees True Sunlight)

The more you think about the particulars of how The Truman Show operates, and the more questions you'll have about the basics of keeping Truman (Jim Carrey) alive.

For one, with his whole life taking place inside a studio-controlled dome with no natural lighting, Truman would suffer from a massive vitamin D deficiency.

In the long term this would cause weak bones, depression, weight gain, cognitive issues, and significantly boost his susceptibility to cancer and high blood pressure.

But the film actually has a sneaky answer for this, as during breakfast Truman has a bottle of vitamin D supplements next to his cup of morning coffee, confirming how the producers keep Truman in tip-top shape despite the obvious risks associated with receiving no sunlight.
