Natalie Portman Will Headline HBO’s New Mystery Series

It's called WE ARE ALL COMPLETELY BESIDE OURSELVES, and it sounds pretty cool.

HBO's been killing it in the mystery department lately, haven't they? Last year we got The Jinx, a docu-series that ended up being one of the year's most compulsively-watchable things. This year's given us The Night Of (note: if you're not watching The Night Of, you're missing out, big time), and now the network's lined up another project that sounds like a winner: an adaptation of Karen Joy Fowler’s award-winning mystery novel, We Are All Completely Beside Ourselves.

And even better: they've scored Natalie Portman to headline the thing.

IndieWire's describing the story as "a 'twist-heavy tale'" centering around a college student (presumably the role Portman would play) whose twin sister disappeared when the pair were five years old. Further plot details are being kept under wraps for the time being, but of course you could read the novel if you really wanted to spoil things for yourself. 

Friends showrunner Marta Kaufman is taking the reigns on the development of the series, while Temple Grandin's Christopher Monger will pen the script. Stay tuned for details as they roll in.
