Hit the jump for casting news on the dramedy Posthumous.

Deadline reports that Jack Huston (Boardwalk Empire) and Brit Marling have signed on to star in Lulu Wang's dramatic comedy Posthumous.  Per Deadline, Huston "plays a struggling artist whose artwork skyrockets in value when he is mistakenly thought to have killed himself. The artist decides to keep up the charade by pretending to be his own brother, but the entire plan is put in jeopardy when he befriends an enthusiastic reporter (Marling) who begins to show him the real value of life and art."  It definitely sounds like a project worth keeping on your radar, especially with Huston and Marling in the lead roles.

Huston will next be seen in David Chase's Not Fade Away and he recently wrapped shooting on Bille August's Night Train to Lisbon.  He also plays Jack Kerouac in the upcoming Kill Your Darlings co-starring Daniel Radcliffe, Ben Foster, and Elizabeth Olsen. Marling is currently working on The Green Blade Rises, and recently wrapped filming on The East, which she co-write with director Zal Batmanglij (Sound of My Voice).  She'll next be seen in Robert Redford's The Company You Keep.
