The trailer for Forza Motorsport 4 contains video taken from another filmmaker without his permission. The cause? A well-meaning but short-sighted director with a first language that isn't English.
The trailer for the new Forza 4 game is mostly made of live action shots from Top Gear USA and two other sources: Clash Productions of France (which Microsoft licensed the video from) and the trailer for the web-series Turn9 by Tim Whitcome (whom Microsoft didn't license the video from).
Microsoft was adamant today indicating they did license those four short snippets of video while the director of Turn9 insisted the video was never licensed to anyone. What happened in between is an international game of telephone gone wrong.
