Surviving Christmas with the Relatives

Surviving Christmas with the Relatives is a movie starring Julian Ovenden, Gemma Whelan, and Joely Richardson. Two sisters and their families spend - or rather, endure - Christmas at their late parents' dilapidated country house.
Two sisters come together to spend Christmas with their families in their recently deceased parents’ falling down country house, with hilariously chaotic consequences, as ancient sibling rivalries flare up again to sabotage the hoped for season of good will.
