My movie has been in the development for a while. It started around Christmas, but took a long while to get all 3 voice-over tracks recorded, edited and aligned to subtitles.
In addition, the Movies game - which is what I used - has infuriating habits of losing the subtitle and sound track locations around if one wants to redo a scene or recut the sequence. And the camera work could have been more flexible. Still, it is better than machinima environments available before (as described in the Wired’s article).
I think my next movie will be about robots. At least there I can get away with a fake voice.
