This was a very strange film. It was set in a 1980’s shopping mall, where a mysterious masked figure brutally murdered many people. In due course, the identity of the ‘Phantom’ is revealed, along with his motives for killing. Also, note the use of Eric with a 'C’. Tsk.
Interestingly, it is one of two 'slasher’ genre films released in 1989 based on the Phantom of the Opera. The other was the lavish production featuring Robert Englund in the title role.
