I think a good question to often ask, is who was the Buddha?
A couple years ago, the BBC did a documentary on the Life of the Buddha. I liked watching this, explaining how the historical Shakyamuni Buddha went from being a prince to an ascetic spiritual wanderer. Someone could probably read about the 12 Great Deads of the Buddha to get a feel for the life of the Buddha, but sometimes its more entertaining to watch it in a film format with animations and music. Not all 12 deeds are in this documentary but its still entertaining to watch and educational at the same time.
