Late Night (2019)

Emma Thompson plays a "The Devil Wears Prada" kind of woman as the late night talk show host Katherine Newbury.  She is dismissive of everyone, to the point of not even learning their names and referring to them by number.  She exploits them in every way possible and then spits them out.
In steps Molly Patel, played by the script writer Mindy Kaling.  She is impulsively hired to add to the writing staff diversity, but she basically has no experience, and spends a lot of time doing due diligence to figure out why the show's ratings are tanking, and figuring out what to do about it.  It is a smart, funny movie that actually takes the late night show genre to task for the lack of women it showcases or embraces as comedians, and does it in such a a gentle and enjoyable way that we really don't mind being shown we have it all wrong.
