The story follows a woman (McCarthy) who is laid off from her job, discovers her husband is having an affair, and decides to go on a road trip with her foul-mouthed, diabetic grandmother. If she takes the role, Janney would play McCarthy’s mother.
McCarthy wrote the script and will direct and produce with her husband Ben Falcone.
Janney starred in last year’s indie dramedies “The Oranges” and “Liberal Arts” and will be featured in “The Way, Way Back”, which is awaiting its theatrical release.
She is repped by Gersh.
