Advent Calendar 2019 Day 18: Carry On Christmas, 1972

Thames made four specials with the Carry On team between 1969 and 1973 (they skipped 1971), notably this third gives three women - Jacques, Sims and Windsor - top billing, if only because Sid James, first named in all three others, was absent (presumably because he'd just made the Bless This House film with the similarly sat out Terry Scott) and Charles Hawtrey then pulled out at the last minute because he wasn't guaranteed to be their replacement. Carry On scholars agree this is the weakest one - Talbot Rothwell couldn't finish the script due to illness and replacement Dave Freeman wrote his own separate material rather than build on what was there, which explains why the central 18th century concept is merely what the sketches loosely hang around and turns into Aladdin about three quarters of the way through.
