Slow Horse star Jack Lowden will reprise his role in The Fifth Step in a new West End production about addiction, faith and masculinity, co-starring Martin Freeman drama.

Loudon made his debut at the Edinburgh International Festival last year in a play written by David Ireland and received critical acclaim for his performance as Luca, an alcoholic who joins a twelve-step program. The double film stars Sean Gilder as Luka's older mentor, a role that will be played by Freeman in the production at @sohoplace in London, which opens on May 10 Performed from July 26th to July 26th. Fin den Hertog will return as director.

The show's title refers to part of the Alcoholics Anonymous program, which involves writing down life experiences that bring you shame and guilt and sharing the list with people you trust. "I realized it was called Fifth Step because the whole show was like my Fifth Step — it was my confession," said Ireland, who attended AA meetings through his own experiences with alcoholism and loneliness. The playwright is best known for his controversial black comedies Cyprus Avenue and Ulster America, in which a Belfast loyalist believes his granddaughter is Gerry Adams , while Ulster America explores the film and theater industries in the wake of the #MeToo movement. The Ulster American Festival also performed at the Edinburgh Festival and later in London with a cast that included Woody Harrelson.

Presented by Neal Street Productions, Playful Productions and National Theater Scotland, The Fifth Step will be fully staged at @sohoplace, a new purpose-built venue owned by Nica Burns. It opens in 2022 as part of a £300 million regeneration of the area near Tottenham Court Road station.

Loudon, who starred in The Almeida Theater's Ghost in London's West End in 2013 and 2014 before finding success in television and film, said: "It's great to be able to work with these two dangerous talents again, David and Finn. Just being in the room, that's a gift in itself, but to add Martin, a black belt actor and a hero of mine, is just the best."

Freeman, whose West End roles include Richard III, called the two-hander a "really funny, disturbing, unexpected play." Den Hertog said Ireland's "iconic acerbic wit, irreverence and subversion are on full display in The Fifth Step". The author said he hoped London theater audiences "will find the play as thrilling, entertaining and thought-provoking as Scottish audiences".
