Rupert Grint, best known for playing ginger-haired wizard Ron Weasley in the "Harry Potter" films, will make his stage debut as a pill-popping thug.
Producers announced Friday that Grint will join the cast of Jez Butterworth's "Mojo," opening at London's West End later this year.
Ian Rickson, who helmed the "Mojo" original 1995 production at the Royal Court Theatre, will direct.
The drama is set in a seedy nightclub after the owner is brutally murdered. Grint will play Sweets, a gangster with an amphetamine addiction.
Following its onstage success Butterworth brought "Mojo" to the big screen in 1997. Butterworth also wrote "Jerusalem," for which Mark Rylance won a 2011 Tony award for lead actor in a play.
Fellow "Harry Potter" alum Daniel Radcliffe has found post-Hogwarts success playing darker roles onstage.
He opted to bare all in the 2007 revival of "Equus" and is currently appearing in the West End production of Martin McDonagh's barbed comedy, "The Cripple of Inishmaan."
"Mojo" begins previews at the Harold Pinter Theatre in October.
