"Grizzly II" was initially shot in the early 1980s.  Or, some of it was shot until the money ran out (a producer left the project).  In 2018, one of the producers, Suzanne Csikos Nagy, returned to the movie and finished it.  That film is out on VOD this week.  We admire the effort that must have taken and wonder what it means about returning/reediting projects in general.
