There is a call for entries for the Wild & Scenic Film Festival - which runs in the US - but accepts submissions from anywhere. We know our alumni includes a fair few budding film makers and we hope they'll pick up this opportunity and run with it:
"We invite you to submit your films: animation, shorts, narratives, kids’ films, documentaries, and features. Foremost, we are looking for films that demonstrate a passion for the art form as well as a clear, potent, and above all, inspirational message. We feature environmental films that cover all issues, as well as adventure films from around the world. If your film is chosen for the 2008 Official Selection, you will be invited as our guest for the festival, January 11-13, 2008. You’ll have the opportunity to introduce your film, speak at filmmaker forums, attend parties, and enjoy a variety of VIP benefits." - Full call for submissions.
