Best Sellers is a 2021 comedy-drama film directed by Lina Roessler and written by Anthony Grieco.

It stars Michael Caine, Aubrey Plaza, Scott Speedman, Ellen Wong, Veronica Ferres, and Cary Elwes.

She must try to keep it afloat in face of a recent streak of disastrous releases, so she seeks the cantankerous, once best-selling writer Harris Shaw for an unpublished manuscript and go on tour with her, but he proves to be hard to handle.

To keep it afloat in face of a recent streak of disastrous releases, she and her assistant Rachel scour their list of former best sellers and find legendary author Harris Shaw owes them a book.

Rachel tries to dissuade Lucy from seeking Harris' help, as the cantankerous old writer has not published a book in 50 years.

He has some unusual stipulations in his contract, including there will be no revisions or editing of his manuscript and Harris in turn is obligated to do a book tour for it.

On the way, Rachel reads out loud rumors about Harris, including being thrown out of Ireland for disorderly conduct and accidentally shooting an assistant.

Back in NYC, just as Lucy is about to sign over Stanbridge Publishing to Jack Sinclair, a reluctant Harris gives his unpublished manuscript to her.

As Harris will not let her edit the book, he must go on tour with her, but his wild antics prove to be hard to handle.

Afterwards, Lucy finds a type-written note in his typewriiter that directs her to a trunk full of unpublished manuscripts in the attic.

Michael Caine was cast to star, with Lina Roessler set to make her directorial debut.
