New Line Cinema has purchased the rights to Gregor Jacobs and William Stadiem's book Mr. S: My Life With Frank Sinatra. According to Variety, Brett Ratner is attached to direct the film.

The novel offers a behind the scenes glimpse into the life of Sinatra and his Rat Pack. The story is told through the eyes of Sinatra valet Jacobs, a role that Chris Tucker may play. Stadiem, a long time chronicler of old Hollywood, is writing the adaptation of his and Jacobs' book.

Stadiem stated, "It's like a love story between two very unlikely people. Brett is a Rat Pack obsessive, and so it's fun to work with someone so passionate about the period. I think he's channeling Frank sometimes."

The film does not have a set start date.
