Viewers will see how he formed a secret company and started up his professional relationship with Thomas Wayne.
Before anyone starts thinking that the Gotham-verse is getting extended in any way, Pennyworth is a complete departure from that project, and Sean Pertwee isn’t poised to be involved.
That’s at least an understandable shame, since Pennyworth will go even farther back into the past, the 1960s, to focus on Alfred in the years after he was a British SAS soldier.
Casting hasn’t yet begun for the central roles, but given this will be the youngest of the Alfreds to make it to live-action, we shouldn’t expect to find any repeat performers in the role.
