Victoria Wood's Mid-Life Christmas

Wood's first sketch show for nine years went out on BBC One on Christmas Eve 2009 and drew 7.45 million viewers. The reason fans seek it out is Beyond the Marigolds, a mock documentary following Julie Walters as Bo Beaumont, the actress who once played Mrs Overall in Acorn Antiques, as she ventures into celebrity reality and dance shows. Wood and Walters also reunite for a spoof of BBC period dramas, and Anton Du Beke, Delia Smith and Torvill and Dean all turn up. Watch it last: it lands best once you know the 1980s jokes it is looking back on.
