Sebastián Silva’s slippery black comedy begins something like a cross between Curb Your Enthusiasm and Girls. Silva plays a version of himself, a film director called Sebastián Silva living in Mexico City; he’s meant to be working, but instead he idles days away on the sofa in his flat morosely snorting ketamine, Googling his own name and researching suicide methods. It’s a deeply unflattering portrait of entitled privilege from Silva and co-writer Pedro Peirano. Sebastián is mean to his dog and unforgivably rude to his housekeeper Vero (played by brilliant Catalina Saavedra, star of Silva’s film The Maid). Keep an eye on Vero, she will be important later.
