Quentin Tarantino has had thoughts of making this project into six episode series with each episode being only 30 minutes long. Whether that remains the plan is unknown at this time.
In a 2019 interview, Quentin Tarantino stated he doesn't believe Leonardo DiCaprio would be open to playing the role of Jake Cahill in this project like he did in Once Upon a Time... In Hollywood (2019) as the character of Rick Dalton portraying Cahill in Dalton's program called 'Bounty Law'.
