Deodato has stated that "I did Phantom of Death because it was based on a true element – the idea of growing old [...] And I got to work with Michael York and Donald Pleasence..."
On the film as a whole, he commented that "some parts look like an 'A' production. But it seemed too long in the final part." He also said that Edwige Fenech was miscast, and only included because the producer wanted her in the film.
Phantom of Death was released on DVD in the UK by Shameless Screen Entertainment. It was also released in some countries as Off Balance.
