The younger Stewart is joined onstage in playwright Mark Brown's "high-spirited, fast-moving and highly imaginative show" by five other actors who collectively play a total of 39 different characters: Evan Zes, John Keating, Lauren Elise McCord, Jay Russell and Mark Parenti.
Cincinnati Playhouse in the Park associate artistic director Michael Evan Haney directs the piece, which is the first co-production between Irish Rep and the Ohio-based theatre company.
