i catch this little gem totally by accident back in 1980 or 81. i be at a revival theatre to see two old silly sci fi movie . the theatre be pack full and ( with no warn ) they show a bunch of sci fi short spoof ( to get u in the mood ) . most be somewhat amuse but this come on and and within second and the audience be in hysteric . the big laugh come when they show princess laia have huge cinnamon bun instead of hair on her head . she look at the camera and give a grim smile and nod . that make it even funnier . you get ta see chewabacca play by what look like a muppet . it be extremely silly and stupid . but i couldn not stop laugh . most of the dialogue be drown out because of all the laughter . also if you know star war pretty well it even funnier they deliberately poke fun at some of the dialogue . this really work with an audience . a definite 10 .
