"Tyderium" was a German fan film project that looks really cool and really high quality, as you can see from the trailer below.
The plot is all about how the rebels actually acquired the imperial shuttle Tyderium for Luke and Han's use.
Alas, as we discussed in my own experiences in fan films a few weeks back, more fall apart than get done. The project seems dead. The last update on their website http://www.tydirium-derfilm.de/cms/index.php?L=2 is dated 2007. I've attempted to contact them to find out more details, but we'll see where that goes, if indeed it goes anywhere at all.
