Once as the children were beyond the age of playing with toys, we've often watched a film between the Christmas Dinner and the pudding. After that we might play cards or a board game.
We are all adults, but the films have tended to be family films as they are easy to watch/follow so can still chat and drink wine.
Definitely don't have to be Christmassy.
Things like the Incredibles, Lego movie, Cars, Wallace & Grommit.
We try to find one none of us have seen, which is the main challenge. Any suggestions please?
