Dear Albrecht,

there is lots and lots of work on these topics, you just need to look. Marco Baroni and others have tried to produce a joint model of picture and distributional word similarity (Bruni et al ACL 2012 Distributional Semantics in Technicolor), Shane Bergsma produced a visual-features model of selectional preferences (Bergsma and Goebel RANLP 2011 Using Visual Information to predict selectional preference).

Most of this work on finding object features uses a combination of color-space distribution and SIFT features (both probably have a decent implementation in OpenCV/SimpleCV).

Movies and pictures can probably be handled by color space statistics quite easily, as this aspect is manipulated in post-production and subject to deliberate stylistic choice by the people making the film or the picture. (e.g., National Geographic style jungle realism vs. modern scifi movie blue-and-orange tints).
