During this period, he performed several major Shakespearean roles, including Orlando in As You Like It, Dromio in The Comedy of Errors, Mercutio in Romeo and Juliet, and Launcelot in Morte D’Arthur.
His work as Mercutio in Rupert Goold’s production of Romeo and Juliet became particularly notable.
The production also toured internationally, including a six-week RSC residency at the Park Avenue Armory in New York.
O’Neill returned to the RSC in 2012 to take the title role in Richard III at the Swan Theatre during the World Shakespeare Festival in Stratford-upon-Avon.
His performance attracted considerable critical attention and strengthened his reputation as one of the notable Shakespearean performers of his generation.
He also achieved acclaim at the Royal National Theatre for his performance as Tristan in Lucy Prebble’s The Effect in 2012–2013, appearing alongside Billie Piper.
His theatre work subsequently included Collaborations, The President Has Come to See You, Talk Show, The Get Out, The Crucible, Cymbeline, The Unreachable, Victory Condition, The Prudes, and Pinter at the Pinter.
He also joined the cast of the crime drama Dalgliesh, playing Julius Marsh. His continued television work has included productions such as Nightsleeper, further establishing his ability to move between period drama, crime, thriller, fantasy, and contemporary television.
