Continuity: When the Swamp thing goes to destroy one of the trucks chasing Cable, the trucks used are chevy blazers but the one he wrecks is a International scout.

Continuity: At the end of the film Kabel gets stabbed in the right side of her décolletage, and she bleeds all over her evening gown, as you would. Swamp Thing very kindly heals the wound. Apparently he also has the power of Magic Dry-cleaning too, because the blood disappears from Kabel's dress.

Continuity: When in the rowboat, Adrienne Barbeau's t-shirt is white in some shots and blue in others. It is not the lighting - it is plainly two different coloured t-shirts.

Continuity: Between Cable being nabbed by the bad guys and escaping by leaping overboard from their boat and the scene where she watches Swamp Thing having his arm chopped off, she alternates between wearing a fairly obvious bra and, well, swinging free, as it were.
