 In the theatrical trailer, Angel Eyes is "The Ugly" and Tuco "The  Bad," which is the reverse of their designations in the actual film.  This is because the Italian title translated into English is  actually The Good, the Ugly, the Bad, not The Good, the Bad and the  Ugly, and the Italian trailer had "The Ugly" and "The Bad" in that  order. When the trailer was transferred to English, The Ugly and The  Bad were not reversed to coincide with the altered title, causing  the incorrect designations.
