My initial reason for watching Tod Browning's 'Freaks' was primarily for inspiration and research for a carnival-esque themed project. Plus the fact it is often cited as one of Diane Arbus' favourite films.
I was instantly gripped and curious, as well as moved. Perhaps some argue it is of its time, yet it's universal truth prevails, it has this strange quality to revert the years, you feel like a child being told a fantastical myth. The authenticity of the actors also makes it all the more profound and touching. Plus the typical old black and white look, especially in the wood scene at the start created this magical aura that not only helps make the film magical but casts this mysterious otherworldly glow.
