In 1968, United Artists gave Richard Lester a million-dollar budget and a free rein, out of which he made what must have been the most noncommercial film he could imagine. In the aftermath of World War III (which lasts for 2 minutes and 28 seconds), Sir Ralph Richardson finds himself mutating into a furnished apartment, Rita Tushingham gives birth to something or other, the BBC makes house calls, the British middle class spends its dying days riding in circles through the remains of the Underground, and civil defense officers Peter Cook and Dudley Moore periodically descend from a balloon to exhort the populace to “Keep moving! Keep moving!” Lester, not too surprisingly, didn’t work again for five years, but this 1969 feature is one of his best efforts, a remarkably sharp and deadly satire. 91 min.
