Amazon hit paydirt with its hit series “Reacher,” and now the streamer is developing a spinoff. Word is that show creator Nick Santora is writing the spinoff with Nicholas Wooton. Exact plot details for the spinoff are being kept under wraps, but it may focus on Frances Neagley, played by Maria Sten. There’s no comment from Amazon yet. Meanwhile, Sten rejoins Alan Ritchson for season 3 of “Reacher” and Anthony Michael Hall, Sonya Cassidy, Johnny Berchtold, Brian Tee, Roberto Montesinos, and Daniel David Stewart are joining the cast.
