The midnight movie favorite in all its gory, goofy and good-natured glory.       When Duane checks into a 42nd Street flophouse, his most cherished piece of      luggage is a large, wicker basket. Inside is Duane's hideously misshapen         Siamese twin, who has been left for dead after surgeons removed him from his   brother's side. Now the two siblings are out to exact revenge upon the doctors who split them apart, but life in New York makes their plan more complicated.  Hilarious, in a twisted sort of way, Frank Henenlotter dedicated this            no-frills freak show to gore-meister Herschell Gordon Lewis. This uncut        edition also includes the film's original trailer and outtakes.                Frank Henenlotter---USA---1982---91 mins.
