In 2012, BBC Radio 4 aired his comedy series "I, Regress". In it, he takes on the role of Dr. Berry, a brilliant but unorthodox regressive therapist. During each 15-minute episode, Berry explores the psyche of a guest patient, attempting to treat his or her problems in surreal dreamlike sequences. Berry appeared in the film adaptation of the David Nicholls novel "One Day", playing the role of Aaron, Dexter's agent. He briefly featured in the closing ceremony of the London 2012 Olympics, introducing ELO's "Mr. Blue Sky" by way of a mock weather forecast.
