Unhistorical evocation of Trotsky's last couple of months in exile in Mexico before the Stalinist agents got to him. Burton as Trotsky is set up very deliberately as a dry, pedantic figure, and his ideas accordingly shrink in importance. Delon, too, as the enigmatic assassin, seems like an unfinished character until the brilliantly shot scene where he watches a bullfight. From there Losey's on his own, fascinatedly turning this key historical event into a Secret Ceremony. We're so starved of hard information that one can only wish for more.
