The actor will star in a production of the Alfred Uhry-penned musical Parade, opening Oct. 4 at the Mark Taper Forum in Los Angeles.
Parade tells the the true story of Leo Frank, an Atlanta pencil-factory manager who in 1913 was convicted in the rape and murder of a 13-year-old female employee. When doubt was ultimately cast on his guilt, Frank's death sentence was commuted to life imprisonment. Soon after, however, he was kidnapped from prison and lynched by a group of citizens.
Knight will star as Frank, while Lara Pulver (Robin Hood) will play his wife, Lucille.
"I am very fortunate to return to the theater playing Leo Frank in this incredible, acclaimed production of Parade," Knight told the Los Angeles Times. "After a five-year break, it feels great to be on stage again."
Knight's previous plank work includes Broadway's Tartuffe.
Parade previews start Sept. 24, with the show running through Nov. 15. Tickets go on sale June 26.
