As far as I can tell, there have been no plans to make a third film starring Antonio Banderas as Zorro/Don Alejandro de la Vega.
Stars of the movie "Desperado" other than Antonio Banderas include Joaquim de Almeida, Salma Heyek and Quentin Tarantino. You can get more information about this film and it's stars at the Internet Movie Database and Wikipedia websites.
