Stephen Bowie writes in his article, "The Invaders: The Nightmare Has Already Begun,"
Frontiere received credit for the incidental music in four of the earliest Invaders episodes. But in addition to writing original music, the composer again cannibalized bits and pieces of his earlier Outer Limits work. The love theme from “Beachhead,” for example, initially appeared in The Outer Limits’ “The Man Who Was Never Born,” and a haunting waltz from “The Forms of Things Unknown” crops up in several early Invaders (and also as the theme for a temporarily blinded Richard Kimble in the Fugitive segment “Second Sight”).It seems fitting to have this connection between the two shows, and probably has much to do with the fondness I feel for it. I recommend that you check out Stephen Bowie's article for more information on Frontiere's involvement and some great behind the scenes information. Be cautioned that he does write in detail about episodes, which you may want to avoid if you wish to remain spoiler free.
The nightmare begins in three more weeks.
