It's almost perfect.
A comedy written by the man who created Fawlty Towers and directed by the man who gave us The Lavender Hill Mob.
I remember settling on Channel 4 when it was shown on Christmas Eve years ago- first time I'd seen it, I was 12, but I laughed so much at the steam-roller scene, I had tears in my eyes.
I love converting people who've never seen it.
