Crikey it’s still roasting, so I’m following John Mills’ fine example –
A bit of trivia about that famous scene, from an interview I saw with Mills. The crew used ginger beer at first but it just didn’t look like lager, so they switched to the real thing. Unfortunately (Mills smirked at this point) it took many takes to get the scene right. When it was finally in the can he was pissed and had to be helped off the stool.
