Now, is it just me, or is this a rather ... strained?... bizarre? ... needless? ... reference to a certain someone?
By covering films in audio wallpaper, usually consisting of contemporary pop or the hideous strains of smooth jazz (a genre then still in its infancy, like a swaddling Adolf Hitler), film-makers ran the risk of making motion pictures that would not only look horribly dated a few years later, but would also sound lame.(Italics, it probably goes without saying, added.)
If you run across any likely competitors in the pointless-reference-to-Hitler category, please do let me know. I think this one is fairly hard to beat.
