Christian Slater has signed on to star alongside James Franco in an adaptation of the hit play The Adderall Diaries.

We haven't heard anything about the project since September 2010, when James Franco purchased the rights to Stephen Elliott's memoir, with plans to star, produce and direct. Now, he is only starring in the adaptation, playing a drug-addicted writer who becomes obsessed with a new murder trial, as he decides to base his new book on the mysterious case. Christian Slater is playing the man on trial, who is accused of murdering his ex-wife.

The book is based on Stephen Elliott's experiences following the Hans Reiser murder trial. Shortly after the proceedings began, the defendant's friend Sean Sturgeon confessed to a number of murders, although he did not admit to killing Hans Reiser's wife. Stephen Elliott was a part of the same BSDM social circles as Sturgeon.

Pamela Romanowsky (Tar) is directing from her own adapted screenplay, with Vince Jolivette (Maladies) producing. The adaptation will be shot in New York, although it isn't known when filming is set to begin.

Christian Slater most recently starred in director Lars von Trier's Nymphomaniac Volume I and Nymphomaniac Volume II
