About (from the video description):-
“Some rare video clips of the matte paintings done for the original Star Wars trilogy and other films. Traditional movie tricks. A topic that still fascinates me. Here I have collected some, sometimes quite rare, video clips for classic matte painting in Star Wars films.”
^ Does anyone know what documentary it is from - or mainly from? I don’t know much about it apart from it is a fascinating watch on how some of the effects were achieved for our beloved films.
