Dario Argento's Third Mother series.
I thought I'd share this with the crowd, mainly because these movies are exceptioanlly renowned world wide for their usage of light, colour, music and camera close ups. They are dated and corny to the modern eye, but they have since received a cult following after their success in the 70's.

Anyway I have always adored the lighting effects in these movies, and giallo (Italian sub-genre of horror movie making) in general. Maybe if you watch these videos you can see my point of view but I thought I'd share with the crowd - might get some lighting tips to use in the future.
