Right now I'm enthralled with the "Production Design and Art Direction" book in Focal Press's Screencraft series.
It features a number of interviews with leading Production Designers. One major thread that appears throughout the book is the fact that the design of a film should be concerned with distilling a visual concept from the story's thematic, emotional, and psychological concerns.
With that in mind, I thought it would be a good time to do a one page treatment of my film idea as it stands today. I think a weakness of mine is to over-research. The solution, I believe, is to hone in as quickly as possible on the thematic and emotional concerns of the story I want to tell, thus making my research that much more specific.
