This question always puzzled me. Altough Warvick states that the original 16mm film of his mockumentary “Return of the Ewok” is lost, the easter egg from original Special Edition DVD trilogy release cleary shows short clip with Bobba Fett and Wicket from “Return of the Ewok” in excellent quality suggesting that the source is in fact preserved.

Does anyone knows is the original film really lost? What was the source for that DVD easter egg edition clip (or it was some kind of alternative source of some other material-documentary where that short clip from Return of the Ewok was simply part of it)?

Does anyone have some additional information on this?
