First Light Online
First Light fund and inspire the making of short films by young people in the UK, reflecting the diversity of their lives.

They have enabled almost 8,000 young people between the ages of five and 18 to write, act, shoot and produce over 500 films. Working with filmmakers and organisations, First Light films cover many topics and genres, and make use of accessible digital film technology.

One useful guide they offer for free is a screenwriting kit to help pupils to develop films to discuss issues of citizenship. The guide can be downloaded from:
