Christian Slater cast in "Adderall Diaries"

June 6th, 2014

Christian Slater is set to join James Franco in the 'Adderall Diaries'.

The 44-year-old hunk will play a computer programmer, Hans Reiser,

who is suspected of killing his ex-wife while Franco, 36, has been cast as a troubled and drug-addicted writer who becomes fascinated by his murder trial.

The film follows Franco's alter-ego, as he begins to pen a book on the dramatic, jaw-dropping case, reports.

Pamela Romanowsky, who will helm the project, also wrote the script based on a ''true-crime memoir'' book of the same name by Stephen Elliott, and Vince Jolivette is set to produce.

The A-List cast also includes 'Pollock' actor Ed Harris and Amber Heard - who is dating Johnny Depp - and filming is believed to be underway in the New York City.

Meanwhile, Slater - who made his film debut with a small role in 1981's 'The Postman Always Rings Twice' - last hit the big screen in 'Nymphomaniac'.

Whilst Franco's credits include 'This Is the End', 'Lovelace' and is also set to star in next year's 'Queen of the Desert' which is in post-production.
