Netflix has debuted a trailer for the upcoming partly improvised crime series featuring Will Arnett, ‘Murderville.’

Meet Senior Detective Terry Seattle (Will Arnett), Homicide Division. For Terry, every day means a new murder case and a new celebrity guest star as his partner. But here’s the catch: each episode’s guest star isn’t being given the script. They have no idea what’s about to happen to them. Together, the guest star and Terry Seattle will have to improvise their way through the case… but it will be up to each celebrity guest alone to name the killer.

The six-episode procedural crime comedy stars Annie Murphy, Conan O’Brien, Ken Jeong, Kumail Nanjiani, Marshawn Lynch, Sharon Stone.
