Truly one of the comic delights of the four seasons of Silicon Valley thus far, T.J. Miller's arrogant stoner character Erlich Bachman will be getting written off the show come Season Five — and the renewal of the series was just announced by HBO Thursday, along with Miller's departure. As Vulture reports, rumors of Miller leaving the show had been swirling for weeks, though the reasons for the decision aren't clear.

HBO's official statement:

The producers of Silicon Valley and T.J. Miller have mutually agreed that T.J. will not return for season five. 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.

The show has two Emmys under its belt and has been a critical hit in its first three seasons, and it's now halfway through Season Four, in which the show's ensemble has had to divide into sometimes cross purposes as fictional startup Pied Piper pivots once again.

The Hollywood Reporter surmises that the reason for Miller's departure may simply have to do with his own rising fame, and hectic film schedule. Miller will reprise his role in the Deadpool sequel, due out next year, and he's also set to appear in Steven Spielberg's Ready Player One adaptation, the Western film Walden, the Kristen Stewart thriller Underwater, and as a voice in How to Train Your Dragon 3.
