I recently learned that George Lucas is backing a new feature length documentary about the 501 Stormtrooper legion entitled Star Warriors. The film is being put together by the same team that brought us the awesome documentary Look, Up in the Sky!: The Amazing Story of Superman.
Someone close to the film told me about the amazing footage they have accumulated from all over the globe. Apparently, Lucas' pull was so strong, he got the 501 legion, which consists of over a hundred members, to march in the Rose Bowl parade. An awesome sight to behold, this entire event was captured on camera.
The editors are still putting the finishing touches on the documentary, which may first air in a truncated version on The History Channel before going to DVD. Don't confuse the film with Heart of an Empire, though. While that, too, is a documentary about the 501 it is not an officially back Lucasfilm project.
