Jonno Roberts has been acting in the US since arriving from New Zealand in 1999. He has become a popular performer on stage as well as screen, performing throughout the US and Europe.

He rapidly gained a reputation for hard-hitting performances in a number of productions that have been acknowledged as American theatre landmarks, including the hit New York production of Tracey Letts' "BUG" (he replaced Michael Shannon in the lead role); as Eilif in Janos Szasz' devastating "Mother Courage" at the American Repertory Theatre; as Edmund the Bastard to Stacy Keach's "King Lear" at the Goodman Theatre, Chicago; and in notorious Catalan director Calixto Bieito's sole American production - "Camino Real", also at the Goodman.
