I saw “Becket” at the Carthay Circle Theater in Los Angeles in the fall of 1964. It is, indeed, a great story—sort of a twelfth-century Watergate scandal. However, at the time, I found the film to be too slow-moving, and so did my mother, who described it as we were seeing it as “a movie that doesn’t move.”
At the time, I preferred films with lots of action, such as “It’s a Mad, Mad, Mad, Mad World,” which I saw at the Cinerama in Hollywood earlier in the year.
IAMMMMW is a good movie too albeit a very different type of good movie than Becket.
