i find this movie amuse for it low budget effect and several flaw in it continuity . the most frequent flaw be the splicing of scene in which it would appear to be day and then night and back and forth . despite and or perhaps because of it flaw and i like it . it do help if you like 1950 b sci fi film and shostakovich to start with . in addition to the plot strongly resemble robert heinlein puppet master and the music be also not original . i could find no evidence that there ever be a tom jonson who write any music for this film or anywhere and ever . most of it be take and uncredited and from dmitri shostakovich symphonies 1 and 5 and and 10. i also recognize an excerpt from sergei prokofiev music score for the russian language film alexander nevsky . at the time brain eater be distribute these composer be not a frequently perform in the u and their music would not have be familiar to almost all movie goer . both composer be from the soviet union ( prokofiev die in 1953 ) . they be perceive a communist and there be a certain amount of prejudice and or or fear about perform it . during the cold war it would also have be difficult for shostakovich to pursue legal action against the film company if he even know his music have be use . i suspect this be exactly why this music be use . i also would not be surprise if it turn out that the source of the performance be record purchase at a record store and the musician be not compensate either . the credit do not list any orchestra ( s ) or conductor ( s ) . the editing of the background music be also poorly do . there be several place where the music do not transition smoothly to the next scene or even within the same scene .
