<P> The film opens with a title sequence of a disembodied mouth ( inspired by the surreal Man Ray painting A l'heure de l'observatoire , les Amoureux ( Observatory Time , the Lovers ) ) against a black background singing in homage to classic science fiction films . It was sung by Richard O'Brien and lip synced , as the now - iconic pair of red lips , by co-star Patricia Quinn . In its original incarnation , The Rocky Horror Show , the song was performed by the character Magenta doubling as the credited role of `` Usherette '' . This character took on the unofficial names of `` Miss Strawberry Time '' , `` Trixie '' and the `` Belasco Popcorn Girl '' from props carried on stage during the number . For the filming of the opening sequence , Quinn 's head had to be strapped to a board to keep it stationary for filming . </P>
