You're in for a bit of a wait for Season 5 of Transparent.
In light of Jeffrey Tambor's dismissal from the Amazon series, production won't resume until the end of this year, meaning new episodes probably won't be released until 2019. Per the Hollywood Reporter, the show was originally supposed to arrive by year's end. But given that creator Jill Soloway and the rest of the writing team are now charged with rewriting the show to accommodate Tambor's exit — it's unknown at this time whether the central character of Maura Pfefferman will be recast or written out entirely — that previously expected arrival date likely won't be met.
Back in February, Amazon announced that Tambor's contract would not be renewed following an internal investigation into sexual harassment allegations made against him by one of his Transparent co-stars and a former assistant. The actor, who maintains his innocence, was effectively fired from the series.
The series will see another big change with Jill Gordon stepping in as the new showrunner beginning with Season 5. However, Soloway will remain with the show as a writer, director and executive producer.
