A scrupulously punctual headmaster in an English comprehensive school sets off for the Headmaster's Conference to deliver a keynote speech. One little slip sees him boarding the wrong train, which leads to a chain of consequences conspiring to keep him from his goal. This is one of the finest farces I've ever seen brought to the screen, written naturally enough by theatre farce-meister Michael Frayn. The frenetic energy of John Cleese in his prime really lifts this above the norm, as he hitches a ride with a student, bumps into and kidnaps an ex-girlfriend and winds up naked in a monastery. The climactic scenes at the HMC amount to perhaps the finest pay-off seen in farce. This is, indeed, a historic moment.
