Dunbar, best known for playing Ted Hastings in the BBC police drama, said: “It’s an honour to be part of the esteemed Gogglebox line-up, especially when it’s raising money for the phenomenal work Stand Up To Cancer do.
“Being able to watch a load of great – and some questionable – TV alongside Vicky and Martin is an added bonus.”
McClure said: “I am a big fan of Gogglebox, really chuffed to be asked, and quite surreal, to be part of the Stand Up To Cancer special with Adrian and Martin. We hope we can help raise much-needed funds for such an amazing cause.
Compston said: “We had such a laugh filming Gogglebox together and we’re delighted to be able to play a small part in the Stand Up To Cancer campaign.
