I figured this blogathon needed a video essay, so here's something I whipped up to help a good cause. I look at how Fritz Lang's "M" is viewed as the prototype for the film noir genre.
This is my contribution to the For the Love of Film (Noir) blogathon being hosted by Ferdy on Films and the Self-Styled Siren. The blogathon has been organized for the benefit of the Film Noir Foundation, who do important work to restore and preserve the noir heritage. You can donate to the Foundation via this Paypal link.
