Comparatively, machinimists using pre-made virtual platforms like Second Life have indicated that their productions can be made quite successfully with no cost at all. Creators like Dutch director Chantal Harvey, producer of the 48 Hour Film Project Machinima sector, have created upwards of 200 films using the platform. Harvey's advocacy of the genre has resulted in the involvement of film director Peter Greenaway who was a juror for the Machinima category and gave a keynote speech during the event.
