Stanley Baxter and the others were very good, too - lots of old English comedy stalwarts, and it was moving to see Graham Hill play a short cameo role. Very sad what happened to him.
There were lots of funny moments, but the film was rather spoiled for me by the madcap drives through busy streets and country lanes. It is not actually funny to see innocent lives at great risk through "comedy" driving. They could have done it without showing scenes where people could easily have been killed or maimed.
