Filth (2013) Jon S. Baird

Bruce Robertson is currently a Detective Sergeant based in Edinburgh, aiming to get a promotion to Detective Inspector. However, his state of mind slowly disappears away from reality as he becomes manipulative and a bully towards his work colleagues. Robertson spends half his time on drugs or alcohol fulfilling sexual fantasies. He gets assigned to the case of a murdered Japanese student and at the same time suffers a series of sever hallucinations, for which he takes medication for bipolar disorder. A series of events that includes his wife leaving him for another man with their child is partially to blame for the decline of Robertson. In order to keep her close to him, he reveals that he dresses up in her clothes.

After Robertson indulges in his lowest point of his career, getting beaten up by the gang that killed the Japanese student, Robertson manages to throw the leader out of the window and kills him, which ultimately gets him demoted. This all ends up too much for  Robertson leaving him no choice but to hang himself, with seconds until his last breathe, he gets a knock on the door from a woman with a child.

Stanley Kubrick's work is evident within Filth. Not just because it's visuals and characters are weird and wonderful at the same time, but also because of some of the environments. Kubrick's fascinating set designs and high key practical lighting can be seen throughout. It could also be linked with his sexual gratification. 

Dr.  Rossi is the resemblance of Mr Deltoid in A Clockwork Orange with his mannerisms and total weirdness.

I don't want to label my character with an illness, but each film i have looked at the character has some sort of problem. Pi - Max looked into the sun for too long when he was a kid, Ed Norton in Fight Club suffers from insomnia, and Robertson in Filth has had a tough history with his wife and kid thats triggered his bipolar.
