It's easy to forget that even now-legendary directors had to start somewhere. Doodlebug is an early effort by Christopher Nolan, about a man trying to kill an annoying pest in his squalid home.
In addition to being in black and white, several of the shots are reminiscent of Memento's noirish vibe, especially the phone receiver in the water. There's also a clear connection to Eraserhead and other Lynchian horrors, with a touch of Rod Serling thrown in for good measure. And the effect looks as if it was made from hand-cut celluloid, a time-consuming effort that might make someone appreciate having the kinds of digital tools that enhanced Interstellar.
