Lee Mack is back for a new series next year, but for now his seasonal special has the usual chaos around a trip out for last-minute gifts.

During its three-year run from 2008, the inter-cultural exchange between Wales and Essex provided some of the best comedy drama of its era. In this Christmas special, the Shipmans are off to the Vale of Glamorgan, and the titular couple are left trying to keep everyone happy while also looking after their son (now 12!).

Steven Spielberg's classic adventure film from 1981 has aged well, and provides a good viewing option for most ages.

This tale of two boys who run away on a white horse was a really big deal when it was released in 1992, and a sure sign of its quality is that it still makes for great family viewing all these years later. Gabriel Byrne and Ellen Barkin add star appeal, but it's the kids who shine here.
Paddington 2 - RTÉ One, 7pm
Excellent sequel that has Brendan Gleeson having great fun with his jailbird character.
Gaybo Laughs Back - RTÉ One, 7.30pm
