KISS nearly broke up after the film because Ace Frehley and Peter Criss were increasingly unhappy. Their manager, Bill Aucoin, suggested that the band split up temporarily and record solo albums. Ace's album ended up with a top single.
Peter Criss was dubbed, because he wouldn't show up to do looping (re-recording lines in post-production). His voice was dubbed by voiceover artist Michael Bell, who did a lot of work for Hanna-Barbera.
According to Paul Stanley in VH1's "KISS: Behind The Music", Ace Frehley often failed to show up during shooting, so Ace's stunt double, an African-American, had to act in some scenes and fill in for Ace on some of the fight scenes. The stunt double's voice was overdubbed to sound like Ace (there are differing versions as to whether Ace or a sound-alike did the overdubbing).
Though exclusively a TV movie in the US, it was released in theaters in several foreign countries. Retitled "Attack of the Phantoms", it featured additional scenes and KISS songs not included in the TV version.
When this was originally shown on "NBC Saturday Night at the Movies", on October 28, 1978, the opening trailer bumper was announced by New York NBC staff announcer Fred Collins, while Peggy Taylor, one of the network's Burbank-based staff announcers, did commercial and ending bumpers.
Almost all of Ace Frehley's fight scenes were uniquely enough his African-American stunt double made up to look like him! Ace was heavily under the influence of Alcohol Addiction by that point in his life as written about in his autobiographical book "No Regrets". And he would repeatedly leave the set because of becoming bored with the long periods required for film production shooting. His stunt double is also mentioned in a booklet of liner notes for KISSOLOGY Volume 2# wherein Ace talks about amusingly convincing others that his stunt double was him actually doing the fighting with a quip about "Taking gymnastics in high school".
