I'm thinking of starting a small film site, which would begin as a simple blog. Imagery from films I discuss on the site would be vital to the look and feel of this site. Instantly though this makes me wonder about copyright/public domain rights for such imagery.

I just wondered if anyone had general or specific advise about using imagery from this industry or another similar situation?

On the one hand I know the film industry aggressively tries to protect its IP (fair enough), but on the other hand, surely film companies do release some imagery of their films in stills format into the public domain to simply help their distribution and advertising efforts?

I have tried looking on stock photo galleries for images of film stills but only found moviestillsdb.com) which seemed very limited in its results.

I've researched a bit about fair usage (http://fairuse.stanford.edu/overview/fair-use/) as well, which I know applies to the USA specifically. This seems to suggest that a still of a film is within these bounds.

Still, any constructive advise others may have as a result of experience dealing with imagery, from film or another domain would be greatly appreciated, assuming it isn't "get a lawyer".
