So apparently from 2007-2010, a movie based on Spyro The Dragon was in development. It was cancelled because Activision was rebooting the franchise with Skylanders, but I found something interesting when searching up the movie. A company called "Velvet Octopus" released a press statement in 2008 that had the movie listed. It had the usual corporate gunk a lot of these press statements have (People involved, Budget, Why it will be a hit), but at the end of the segment it said this. TEASER TRAILER AND TREATMENT AVAILABLE.
It says that you could download trailers from their website, but it has since been deleted and uses a lot of dead flash links. Maybe there's an upload of trailer online. If anyone knows were I can find it, let me know.
