Director Michael Powell and his frequent collaborator Emeric Pressburger (known as The Archers, they co-directed, co-produced and even co-wrote many films) are in my opinion some of the best British directors, with such amazing films as Black Narcissus and The Red Shoes to their names.
Powell was always more associated with the direction of the films, and Pressburger with the scripts, and while that is generally how they worked they did pretty much everything as a duo.
After many years of working together and having raised their names alongside other great British directors such as David Lean and Carol Reed, they parted ways to explore different projects, Emeric Pressburger continued writing scripts for many years and Michael Powell directed Peeping Tom, one of the most infamous films of it's time. This film effectively ended his career as it was almost universally panned and labelled as pornographic, which is absurd.
Although Powell did direct about five other films, they were mainly failures due to the bad reputation caused by this film and his career was entirely finished by the early 1970's.
