film making tips

After reading the article 6 film making tips from joss whedon ive learned that he created the show buffy the vampire slayer. Ive learned that working in film is a very tuff profession because you need many key components to make just a show let alone a whole movie, and lastly i learned that he was one of the writers for the horror movie The cabbin in the woods. In my opinion the article was full of information and was well written. some of the videos posted in the article were very interestin such as the buffy the vampire slayer one. what other movies will joss direct or write?
