The Last Word (2017) online

A one-time highly successful business woman, Harriet Lawler (Shirley MacLaine) has micro-managed every single aspect of her life. Why would her obituary be any different? And so she assigns the task to a local writer, Anne Sherman (Amanda Seyfried). When the first draft doesn't meet her expectations, Harriet sets out to rewrite her life's story before it's too late, with Anne dragged along as an unwilling accomplice. But as Anne slowly comes to realize, it's not Harriet's legacy she's helping to shape, it's her own.
