Please Kill Mr. Know It All is a 2013 romantic comedy film directed by Colin Carter and Sandra Feldman and starring Lara Jean Chorostecki, Jefferson Brown, Kristina Pesic, and Cliff Sanders.
Although she'd like to be a novelist, she makes ends meet by ghost writing a local advice column under the pseudonym Mr. Know It All.
After a celebrity endorsement turns her column into an overnight success, the newspaper requests a photo of the author from Sally's agent and best friend, Patti.
Once the picture is published, Albert can no longer walk down the street without being recognized, and so, for the sake of his livelihood, he decides that he must kill Mr. Know It All.
Meanwhile, the girlfriend of Albert's Mob Boss decides to pack up and leave after being inspired by the advice given in one issue of Mr. Know It All's column.
