A Film with Me in It (2008)

"A black comedy about screenwriting and slightly fatal accidents"

A dissolute scriptwriter and a dejected actor become unwittingly drawn into a labyrinthine mess when several people experience bizarre accidental deaths in their flat. Though the men didn't deliberately cause any of the incidents, they fear that they will be unfairly pegged as murderers if they relay information to the cops, and promptly set about disposing of the corpses in gruesome ways.
