A documentary that you must all watch...
I watched this about six month's ago. I've always believed in the power of high dose vitamin intake and this film confirmed it to me. 5 stars on IMDb with nearly a thousand votes. I've included the trailer below and a link to the site. I'm sure you can find it for free if you search for it.
