“The producers of Silicon Valley and T.J. Miller have mutually agreed that T.J. will not return for season 5,” HBO said in a statement. “In Erlich Bachman, T.J. has brought to life an unforgettable character, and while his presence on the show will be missed, we appreciate his contribution and look forward to future collaborations.”
This is bad news. I recently got into Silicon Valley on HBO Now, and enjoy it immensely. Bachman is one of my favorite characters. It'll be interesting to see how producers write him out of the show, and how things will look after Miller's departure.
