Are there any other issues or advantages that you're able to see that would be unique to movies? While I'm unable to think of a use, seems like there's the potiental for side channel analyis via music, dialog, background-noises, scripts, etc.

Script analysis would take much more effort probably, but it could work if the colour is in the movie script...in that case object detection gets important as well. Just using more training data to cover all the dog breeds and car colours would help a bit though.
