"Alltop" has a new blog portal on Film making. It collects the top blog sites (and their recent posts) all on one page. The site itself has been set up by the unstoppable web legend that is Guy Kawasaki. It is similar to the Scribomatic really - but for film making. And there is a screenwriting one too - featuring the usual suspects of the John August / Danny Stack variety.
I think both of these offer a great one-stop page to point people towards if they are looking for an insight into film making or scriptwriting. A fantastic launching point. Bookmark it.
