Richard Lester’s “The Four Musketeers” was filmed at the same time as his 1974 hit (which was, uh . . . “The Three Musketeers”) and continues the same story with the same combination of impenetrable plotting and nonstop swashbuckling. I liked the first film better than the second, but in any event, half of this pair is enough. It’s too much of the same material, spun out into a wearying series of sword fights and romances.
