Fox have released a small featurette regarding Alfred Pennyworth and Bruce Wayne's relationship throughout [Gotham](series:1127075), with commentary from Sean Pertwee (Alfred), David Mazouz (Bruce), Danny Cannon (Director/Executive Producer) and Bruno Heller (writer/executive producer.)
It's a nice little examination of their relationship and where the show is going to take it. It also offers some insight into why Alfred might start gruff and end up being the incredibly caring butler he is already shaping up to be. On top of that, the fight training between Bruce and Alfred is quite reminiscent of the Alfred we see in Earth One- if you were wondering why Alfred is the way he is in [Gotham](series:1127075) - that is, quite gruff, tempered, and more intimidating than we've seen him in live action- be sure to have a read of my article here.
Have a watch.
In addition to that, if you like the things like Wayne Manor selfies and news from the actors behind the characters, I'd invite you to check out Sean Pertwee's Twitter, where I got that photo, as well as David Mazouz'! The vast majority of actors in the show seem to hold a very active social media presence.
