Darryl Clark has appeared on Coronation Street in four roles:
- A Police Constable who, in October 1997, alongside Det Sgt Neil attended a call by Alma Baldwin, worried that an unhinged Don Brennan was watching the Baldwins' flat following his escape from Weatherfield General
- An Electricity Man who cut off the supply to 5 Coronation Street in February 1999 as the Battersbys had neglected to pay their bill (however he returned to reconnect them when he installed a prepayment meter).
- A Desk Clerk who was on duty at Weatherfield Police Station when Tony Gordon handed himself in for the murder of Liam Connor in November 2009.
- Seth Smithson, who between April and May 2018 worked alongside Jude Appleton in Weatherfield Marine Life Centre's gift shop.
Having completed a three-year Dramatic Arts course at Bretton Hall, he has also been credited for roles in The Cops, Where the Heart Is, Clocking Off, Holby City, The Bill, The Royal, Emmerdale, Spooks:Code 9, Accused, Doctors and Shameless.
