As part of the BlackBerry Keep Moving Projects, director Robert Rodriguez is making a short film with the help of BlackBerry fans. Dubbed Project Green Screen, the film will add in photos and ideas from fans to create a final product. For the next portion, Robert is asking fans for their crazy ideas for a weapon that will appear in the film.

For Act 2, we need a creative genius with just a hint of madness. Watch Act 2 below and you’ll see a villain-slaying weapon, still partially in green screen. Tweet your wackiest ideas for what the weapon does, and you could help shape the story.

You can tweet your weapon ideas to @rodriguez using the hashtag #KeepMoving. The ideas must be submitted by Wednesday April 10th.
