Antonioni’s film Blow Up is a confusing film about an arrogant photographer who believes he has witnessed a murder. The aesthetic of the film is typically 1960s. The streets of London are (improbably) quiet. Through the streets march loudly protesting students, and artists performing.
Compared to Blow Up, the Sound of Music, which runs here in the house down the road, is an aural mess.
The fact of the murder being unconsciously photographed reminds me of the childhood series Q and Q. Wikipedia confirms this association.
An alienating tennis match in mime at the end of the film also leaves the photographer and the viewer confused.
