Life inspires art, and art inspires life. Anyone that is artsy in anyway, knows this is true, and many of our favourite movie and series characters have been inspired by real life.
I grew up on Dragon Ball in high school, and was enthralled by it, little did I know that this axiom was true for ol' DB as well. This video really opened my eyes to some really awesome things. Now I'm really clued up on my favourite comic and super hero back stories and easter eggs, but back when you were a kid, you don't always know these things, just have a look at this video that really goes into some cool details about how Dragon Ball was made and who inspired some of the villains and backdrops.
