A rehook is a film which is so powerful and appealing that cinema goers go back for repeat viewings. These blockbuster shows keep the box office coffers full. Good examples are classics like “Gone with the Wind”, “Titanic”, even the Bond series. New hit “Inception” is another rehook, with many people returning for repeat shows, but more because the plot is so complex that viewers want to make sense of it. This is the power of the rehook.
