What should you put on your personal film website? How about film you've shot, and updates on what you plan to shoot? Also you could put your film resume on there. Maybe a blog.
Look at other film company sites. Some are flashy...some are simple.
As an example of a simple film maker's site which I really admire: www.pentaworks.org
If its for you as a filmmaker, then a resume/show reel type website is good. You can direct potenitel employers there instead of pasting your resume in an email.
If you are a company or trying to start one, then a comapany style site is what you'll need.
