Ideas for what to do at a club?

Due to my recent anti-bullying video, (currently available to view on the Didcot Girls School homepage), I have been asked to start a movie-making lunchtime club for Year 7's and 8's. However as I simply adore the French language I'm integrating French into this club. For example they'd make a movie and give it a French voiceover. Does anyone have any ideas of what I could do at this club or how to structure the club time? Thank you!
