Basket Case

A gory horror film about a pair of Siamese twins--one normal, the other gruesomely deformed. The pair is surgically separated at birth, and the evil disfigured twin is tossed in the garbage. Fraternal ties being what they are, the normal brother retrieves his twin--essentially a head atop shoulders--and totes him around in a basket (he ain't heavy). Together they begin twisted and deadly revenge, with the brother-in-a-basket in charge. Very entertaining, if you like this sort of thing. Followed by two sequels, if you just can't get enough.
