 There are two versions of "The Guardian":  the theatrical cut, credited to  William Friedkin, and a modified cut, credited to "Alan Smithee".  The Alan  Smithee cut has never been released on video but has been shown on cable.  It  includes new scenes including another scene in the hospital; different dream  sequences; a scene of the nanny waking the wife up and alternate angles for  other scenes.  Also, the ending of the cable cut is different and omits much  of the gore.
