Where have you seen Quinny's parents before?

We're experiencing some amazing acting from Mikey North as Luke "Quinny" Quinn's parents visit Gary to hear the truth about Quinny's last moments in Afghanistan.

If you're thinking they look familiar, Ian Quinn is being played by Christopher Middleton - who I know from And When Did You Last See Your Father? - and Lizzie Roper, who was in the frankly excellent Angus, Thongs and Full Frontal Snogging.
