Skeletons in the closet

Everything's a bit askew. What Remains is a film done by a Chinese production team (directed by Ran Huang), it's shot in Finland with a cast of mostly Swedish and Finnish actors (Stellan Skarsgård as the heavyweight) and they all speak English. It seems so unrealistic that it inevitably makes weird nordic noir. Based on the case of Thomas Quick, a Swedish man believed to have been a serial killer who confessed to more than 30 murders while detained in a mental institution.
