Recently pulled into the spotlight by starwars.com, the white prototype armor for Boba Fett was first seen in a 1978 screen test.
See the video at http://www.bobafettfanclub.com/news/bounty/remembering-boba-fetts-prototype-armor/
In the clip, sound editor Ben Burtt introduces the viewer to Boba Fett, as portrayed by assistant editor Duwayne Dunham. In later photos, Alan Harris models the suit.
In the video, they test out a lot of Boba Fett's armor and weapons. He also temporarily has a Star Wars beach towel.
Thoughts on the video itself?
