This pervy clip is an excerpt of António da Silva’s short film ‘Bankers’, playing next week at the Berlin Porn Film Festival. In the tradition of William E. Jones’ Mansfield 1962, the film is made up of footage he shot surreptitiously over a period of one year in a couple different cottages in London‘s financial district.

Around lunchtime — 12:30 to 2:30 P.M. is the peak time for a wank with a banker apparently — António would head down to Canary Wharf to the squeaky-clean toilet frequented by the horny gentlemen working in financial services. To fit in, he dressed the part (button-down shirt, grey slacks) and sandwiched his Canon EOS 5D Mark II between a gym bag and a jacket to hide it from view.

Since António would enter the tearoom with the camera already recording and never look through the viewfinder, he couldn’t see exactly what he was shooting until he returned home to upload the footage. He explains: ‘It was very exciting for me to go home to see what the camera was able to capture’.

More exciting than a handjob? Clearly getting a great shot is more thrilling than actual sex when you’re a peeping tom.

‘Bankers’ plays at the Berlin Porn Film Festival on Thursday, 25 October from 7:00 P.M. and Saturday, 27 October at 10:45 A.M. and 1:30 P.M. For more info, check out the full program. More on Antonio’s work can be found on his tumblr page.
