Pink Floyd The Wall is a 1982 musical film by British director Alan Parker based on the 1979 Pink Floyd album The Wall. The screenplay was written by Pink Floyd vocalist and bassist Roger Waters. The film is highly metaphorical and is rich in symbolic imagery and sound. It features very little dialogue and is mainly driven by Pink Floyd's music. The film contains fifteen minutes of elaborate animation sequences by the political cartoonist and illustrator Gerald Scarfe, part of which depict a nightmarish vision of the German bombing campaign over the United Kingdom during World War II set to the song "Goodbye Blue Sky". ) In my opinion Wikipedia is not always trust worthy so I double checked that answer and looked up his site and it checks out: very interesting art if I may say so
